Burb tank for a 70K10

[70K10Hunter]

I am gathering parts for my K10 build, and just like most I will relocate the fuel tank between the frame rails where the original spare tire went. I have heard most use the Blazer tank couldn't find one so I scored a burb fuel tank out of a 89. Called the Chevy dealer and found out it is a whopping 40gal Yehhh Buddy!! got some capacity now. Measured to the top of the filler tube it is approx. 15" high. I guess it will stick down a little further than maybe anticipated but no worries the truck will get lifted and I will build a bullet proof skid plate for it. The truck I'm building had the aftermarket saddle tanks on it with the tank selector valve on the driverside floor, not gonna need those anymore! the tank I am using is from I believe a fuel injected TBI engine(not sure) any way got the filler tube the tank and the pump for 60 bones. Does any body know what fuel pressure those pumps run at? I haven't decided what engine I will use yet. Could I use this pump setup with a carb, and fuel pressure regulator?

Yes you could run that pump but you are still going to need to run a regulator as they run too high of pressure for your carb.

If I run a regulator will it make the pump run too hot and shorten its life? I know the fuel cools these pumps but just saying?

I am doing this exact swap. Theres more photos in my build thread. It actually bolted in very easy. I havent got the fuel filler/door worked out yet until i get the bed back on. I'm going to fab in a fuel filler door behind the wheelwell ( got the door and hinge assembly off a 86 blazer). But anyway, I would not use that pump with a carb. It's almost 35 psi vs 5-6 for a carb. I'm running pro-flo (EFI) and I need to contact edelbrock and see if the stock pump (454 TBI) pump will work. If not, I'll stick with the external pump and mount it on the frame.

yeh wow thats too much pressure, if I stay with the carbed engine I will probably gut the pump/pickup assembly to maintain my fuel draw and guage.

I'm gathering parts for almost the same swap. I needed a pump to put out @50 psi for the '97 454 that I'm swapping in. I went to Napa and got stock '97pump for a 454 and replaced the one from the '89 Blazer tank which put out@ 35 like you said. They looked and fit identical. K10Hunter- you could probably just remove the pump from the '89 tank, extend the pickup to where the bottom of the pump was and just use the stock mechanical pump on your engine. I'm not sure about the gauge compatibility though. The new sending unit is something like a 90 ohm and the gauge in my '63 is a 30 ohm, so I had to re-wind the sending unit to work with the original gauge. Not sure when they went to the higher ohm gauges.

[70K10Hunter]

Yeh on the later models they bumped the ohm rating to 90, I believe that is what is standard nowadays. I think it was 66 or 67 they made the change.

Sunsoaked: I remember reading your thread when I first found this site so I checked it out again, you are farther along than me. Yesterday I picked up a bed floor and did the needed few minor repairs (welded up some holes)I am not looking to build a one off truck just a quality all around/hunting rig, so now that you mention it I will have to go get a fuel door assy and do the same as you and fab it in.
