Burb Gas Tank for EFI Conversion?
 

Have seen several threads on the 63-66 pickups and underbelly tanks, but not many focused on the Suburbans... Looking to do a "LS" swap (5.3L from 3rd Gen GM truck) on my 1965 Suburban and have been looking for a replacement tank with in-tank pump. It looks like there are a few options I've seen, but not all are setup for the in-tank pump.

Rick's Tanks - GM TRUCK 1963-66 - Part #135001 Side Fill, 135002 Cap Fill, 135003 Bed Fill. Does not list Suburban but says it's side fill. Does it work with the Suburban?

Boyd's welding - Does not list Suburban but says it's side fill.
https://fueltankparts.com/collection...ealth-340-pump

No Limit - 19 Gallon. Not Suburban specific but has side fill option... We can outfit our tanks with a side fill port for those who want a clean bed floor. Typically a custom door is then installed into the bedside or fender. A small "c" notch (included) may be required for frame clearance.

1991 Suburban tank - I believe it's an EFI tank but for TBI, pushing <20 psi? Is it easily converted to a higher flow pump?
I haven't seen any specifics where someone with a 63-66 Burb have installed one of these. I read thru all the more recent Suburban build threads in this forum so I can't say I've read them all... Wondering about what fitment issues are there with the side fill location of the 1991 tank? How does it line up with the existing fuel door on the 63-66 Burb?

Other ideas I ran across but would require running an external pump:

Anybody converted their original tank for an internal pump? to keep the spare under the truck?

Re: Burb Gas Tank for EFI Conversion?
 

I have not seen anyone reproducing a 63-66 burb tank with the proper spare tire cutout. The usual aftermarket tanks do fit in the stock, burb location, so that's probably why all the vendors say it is for the burb

Here is info on one from Holley you might find helpful:

Re: Burb Gas Tank for EFI Conversion?
 

Thanks! This one and the Tanks one look similar, would like to find someone who has installed one of these side fill tanks on a 63-66 Suburban, to see how the side fill lines up to the stock Burb fuel fill port.

Re: Burb Gas Tank for EFI Conversion?
 

I'm fairly certain you will have to do a little custom fab work to mate back up with the original filler regardless of which tank you go with. The positive is that you will have a brand new tank with modern internals (and potentially a brand new filler tube to the side fuel door), well worth it imhp. Keep us posted on your progress and good luck!

Re: Burb Gas Tank for EFI Conversion?
 

Roger that, appreciate the feedback! Given long shipment times for parts these days, I want to try to make sure I get it 'right' the 1st time. For example, $584 for a Tanks one with pump and sending unit vs a Boyd's tank with all that installed for ~$250 more? Which one requires less fitment issues to deal with, requiring fab work and/or additional parts. I know this is all part of the hot-rodding experience, solving these issues, but don't need too much of that... lol

For example, Tanks has a bunch of filler hoses of various shapes, https://www.tanksinc.com/index.cfm/p...rod/prd104.htm
Maybe I'll be the first to do this and get to report back here.

Re: Burb Gas Tank for EFI Conversion?
 

Thx, are the pick-up and Burb frame the same where the stock Burb tanks fits?Would be nice if these aftermarket ones used the same one-strap design as the Burb. Lots more Pickups than Burbs I reckon.

Re: Burb Gas Tank for EFI Conversion?
 

Yes, the frame is the same where the gas tank mounts. I believe the aftermarket ones use the two strap design similar to the 67-72 Burb.
There are lots more pickups than burbs, and since the frames are the same width as the 67-72 burbs, the aftermarket companies don't spend the money to make a tank with the spare cutout

Re: Burb Gas Tank for EFI Conversion?
 

CPP makes one with intank pump for EFi, no cut out tho.

Re: Burb Gas Tank for EFI Conversion?
 

Which one? This one @$1,162? SS but does not include the EFI pump or sending unit...
https://www.classicperform.com/Store...uck/SS632C.htm

There's one that's intriguing, says for Suburban, 26 gallon, but not EFI.

Clyde,

Nice truck! Do you have another photo of your truck from behind? http://67-72chevytrucks.com/vboard/s...2&postcount=75
I see you have a Boyd's tank, wanted to see if it's visible hanging down?
Thx!

Re: Burb Gas Tank for EFI Conversion?
 

Hey Roy,
I am also looking for the best fitting tank for a 66 GMC suburban (carryall).
What I notice on all the side mount aftermarket tanks is the side fill comes from the top and not really the side like the originals. I think there might be a contact problem with bed boards plus a slower drop to the tank when filling because of the angle to the filler door. And nobody wants one that hangs below the bumper. Mine has a 1995 TBI engine so I also would want an in-tank pump.

Perhaps there would be enough interest in these that some company might custom make one that addresses all the issues and would work for all the suburban/carryall owners.

Please keep us posted on your experience and I will search also for custom fab...

Re: Burb Gas Tank for EFI Conversion?
 

I installed a boyd efi tank on my 63 suburban for my ls1. I had them change the fill location and the size of the fill pipe on the tank so it matched right up to the original fill pipe. the tank works good for my application. My suburban is lowered in the rear 5ish inches and you cant see it that much from the back. i can take pics if you would like for reference.

Re: Burb Gas Tank for EFI Conversion?
 

RoyL,

Thank You!

Here is a rear view of my truck.

Re: Burb Gas Tank for EFI Conversion?
 

RoyL, here is the tank I got.

Re: Burb Gas Tank for EFI Conversion?
 

Yes please share some pics, thanks.

Re: Burb Gas Tank for EFI Conversion?
 

Yes, photos are always much appreciated! I know it's close quarters under there, I could not get great clear pics of the stock filler plumbing...

Re: Burb Gas Tank for EFI Conversion?
 

Clyde,

Thx, can't see the tank hanging below your bumper... that's good to see. Looking at the link, it's a Suburban 26 gallon tank, there's a sketch with dimensions, 13.3" tall and 21.3" long. Is this the one you have?

Re: Burb Gas Tank for EFI Conversion?
 

clem,
Thanks for joining in on the discussion, will also share whatever I find and end up doing. You said you have a TBI, so you may have option of a Suburban tank from the 90's, I can't find the link where someone said what year(s), but they would already be set-up for the TBI pump in the tank?

Re: Burb Gas Tank for EFI Conversion?
 

Here are the pics on my burb...Boyd tank with altered fill to match up to stock fill location.

Re: Burb Gas Tank for EFI Conversion?
 

thanks for the pics! Looks like the filler and vent are a straight shot to the new tank, no turns? Do you have the dimensions of off-set from the boyd's "stock" side fill tank?

What capacity is your tank?
Thx!
Roy

Re: Burb Gas Tank for EFI Conversion?
 

Looks like the filler tube is about 10" from the rear brace

Re: Burb Gas Tank for EFI Conversion?
 

The boyd tank is 19 gallons, My fill is 10.75 to center of pipe from front of tank and I left how it was placed from side to side in their standard location. It would be to your benefit to move that in a inch or two so when you install you can put it straight up and not have to angle into position. The pipe size is 1.5" also. The only issue i had with this setup is i also bought the rollover vent i think it's called but due to the location of the fill it would keep it closed when filling and not allow the tank to breathe causing it to always shut off. i ended up taking it out.

Re: Burb Gas Tank for EFI Conversion?
 

All us 60-66 Burb owners sure appreciate the info, feedback and pics you have shared to date. I am curious about the roll-over vent you removed.
-How is your tank vented now?
-Are you using a vented gas cap? if so which one and do you get any gas seepage/spill on spirited turns?
Thanks!

Re: Burb Gas Tank for EFI Conversion?
 

Thx for the info! Can you please clarify what you mean by the above in blue?
Confused as to where the "standard location" is?

Re: Burb Gas Tank for EFI Conversion?
 

the rollover vent is supposed to stop fuel in a case of a accident. it is basically a check valve and when pressure is applied it blocks the hole. i took it out and just used a stainless steel 90 degree thread to tubing fitting and bent a piece of 1/2" s.s. tubing and used that for my return to the original location with a small piece of rubber in between the two. I figured if something was going to happen it really doesn't do much if i have a rollover that will stop the fuel but right next to it is the main fill line that has nothing stopping it. I used a new cap i bought with the tank from boyd but i cant remember if its vented or not. I'll double check and let you know.

Re: Burb Gas Tank for EFI Conversion?
 

Thanks lownslow64. My understanding of the design on the original tanks is that the smaller tube which leads back to the main fill tube (terminates just below the gas cap) is to help prevent gas from splashing back out (fill pressure) when filling the tank. If using a stock style fuel pump, tank pressure increases/decreases when driving, when ambient temperatures change etc. A vent is required somewhere to help with this, in stock form I believe the original gas cap was vented. My current gas cap, even though it's aftermarket, is also vented and helps with this. The only issue I have from time to time is a small amount of gas seepage from the vented cap if tank is more than half full and I take some hard turns.

Re: Burb Gas Tank for EFI Conversion?
 

Can you clarify what you mean by "My fill is 10.75 to center of pipe from front of tank and I left how it was placed from side to side in their standard location. It would be to your benefit to move that in a inch or two so when you install you can put it straight up and not have to angle into position." Do you mean move it in 1 or 2 inches less than the 10.75"? Or you would move their "standard" location? Not sure what the standard location is...?

Re: Burb Gas Tank for EFI Conversion?
 

Sorry for the delay... To clarify of the post previously i altered my fill neck 10.75 from front of tank to Center of new fill pipe which i changed to 1.5" to match existing fill on 60's suburban. i was suggesting to inset the fill 1.5"pipe maybe a inch or so towards the center from there standard which shows 9.75 from center because i installed mine with my burb on jack stands using a floorjack i felt like i had to angle it a bit to get it into place as well as line it up with the brackets you mount to the frame for installation. It would just move the end of the fill pipe inward a bit to not be a comflict during install. It wasn't a huge pain but just a suggestion for my installation method. if you have a rack and more space available it probably wouldn't be such a problem. Let me know if that makes sense.

Re: Burb Gas Tank for EFI Conversion?
 

Thanks! just making sure I understood...

So you would move the filler port and vent ~1" inward/closer to the center, 8.75" vs the standard of 9.75"

and use 10.75" from the front of the tank vs the standard 14.642"?

Reposting the diagram, since it cut off the left side dimension showing the standard filler port location of 14.642"

Re: Burb Gas Tank for EFI Conversion?
 

Yes, i would move the filler 10.75 from the front of the tank and 8.75 from the center and change pipe size to 1.5" to hook right up to the existing fill. That will allow you the right size pipe, location to hook up and allow you the space to install without fighting it to much...good luck!

Re: Burb Gas Tank for EFI Conversion?
 

Thanks!

The Bad News: I tried to order from Boyd's but they are NOT doing any custom work... apparently new for 2022, you can only order existing products. however....

The Good News: They said Pro Performance offers a 63-66 Suburban tank!

From Boyd's: "The tank requested is very close a Suburban option that is available through one of our dealers, Pro Performance. These tanks are made to order by us and ship from our Florida location. Here is a link to the SUV tanks on his website: https://azproperformance.com/collections/boyd-welding-60-72-c10/products/boyd-aluminum-gas-tank-side-fill-67-72-2wd-blazer"

Anybody used one of these? I'm trying to confirm with Pro Performance the filler location to see how close is 'very close'... Stay tuned.

I did see Pro Performance has a build thread on a 64 Burb, but couldn't tell what tank they used... http://67-72chevytrucks.com/vboard/s...5&postcount=46

Re: Burb Gas Tank for EFI Conversion?
 

According to Pro Performance, this photo shows where the filler is located, they said that this is an old design, they have added the filler vent tube to all side fill tanks now. It looks to be right about where it needs to be...

Re: Burb Gas Tank for EFI Conversion?
 

When I ordered mine I spoke to the owner travis and he was in the process of making a suburban option through boyd because that was his suburban and there was no option for them without alot of work. I would call them and talk to travis and go over the measurements for verification.

Re: Burb Gas Tank for EFI Conversion?
 

I PM'd Travis and ordered from another ProPerfomance guy. No forum discount though... lol. Ordered on 28-March and received it 28-Apr.
Here's a few pics, will post the fitment once I get there.

Filler tube does not protrude out from the tank like the stock one, but appears to line up pretty good front to back.

Re: Burb Gas Tank for EFI Conversion?
 

Thanks RoyL, those are some very helpful pics and that is one nice looking new tank. Almost a shame it hide it up under a truck ;) looking forward to your fitment updates.

Re: Burb Gas Tank for EFI Conversion?
 

Royl- Tank looks good. they made some nice improvements to it. Let us know how the install goes.

Re: Burb Gas Tank for EFI Conversion?
 

A bit of an update, got the tank mocked up yesterday.

Filler tube could be 1" or so further rearward for perfect alignment, as recommended by lownslw64. Measured the tank and it's ~9" from the front edge of the tank. He suggested 10.75" Mounting flanges line up nicely, have about a 1/2" clearance front to back inside the cross braces. Interesting note, the front cross brace near the axle is slightly angled, apparently to allow room for the stabilizer mount. Y'all probably knew that... I thought I didn't have the tank lined up right, but it was the cross brace.

Great pics and updates, nice to get real feedback on this tank install. Keep up the great work and keep us posted!

Re: Burb Gas Tank for EFI Conversion?
 

Any more updates? My long-term goal is EFI, and I'm currently having fuel pump issues. was half thinking about investing in a new tank and electric fuel pump now instead of replacing the mechanical... might as well, right?
