Project: '72 Family Hauler

[shearjs]

I’ve taken a break from wiring to work on the fuel system. I have everything needed but just need to make it fit and put all the pieces together. It looks like this 31 gallon tank should fit well. I also bought an Aeromotive Stealth 340 to swap into the Blazer tank stock sending unit. While everything is apart l, it seems like the perfect time to install the Deadend Garage c-notch that I’ve had for way too long now. The Burb was lowered when I bought it so I’m not quite sure what size drop springs are on the rear. They feel pretty sloppy with the added weight of the Burb over a truck. I’m considering going to a taller spring (4” drop) and using a lowering block to make up the difference and allow for more spring travel. Does anyone have recommendations on a coil spring now that ECE is no longer in business??

I originally had 5" truck rear springs and it rode terrible. Cpp has a 4.5"hd spring ment for the suburban, swapped to that and rides great now

That’s good to hear. Are the HD springs thicker than the regular drop springs or are they just taller? The pictures from their website all look the same.

The standard posi uses a spring to engage both Axel's. The trutrac uses gears instead of the spring. Check out this website

Thanks very much....that was very helpful!

[shearjs]

Thanks for the real world responses. I will likely go with the Truetrac. This is my first complete rearend rebuild by myself so I’m looking forward to the challenge.

I don't know diddly squat about Suburbans. Any idea why there's plywood on the floor?

That is standard for the cargo area of a suburban. Basically like a truck bed.

I honestly don’t know why they went with a plywood floor instead of steel either.

I took a week off work to focus on the Burb. The to-do list included installing the Deadend Garage C-notch, painting the rest of the rails, moving the rear crossmember to install the 31 gallon fuel tank, mocking up the fuel tank, swapping springs to the CPP 4” HD, completing the rearend rebuild(ended up with a Truetrac and 3.73 gears), and running new brake and fuel lines from front to rear. I initially added the one inch blocks as well but I think it would be too low with the weight of the vehicle so I pulled those back out for now. I also have a No-limit rear sway bar that I tried to snake between the body and top of rails but I just didn’t have the ability to raise the body high enough to get it through. Maybe I’ll try again at a later date. I’m close to having the fuel pump wiring sorted out to maybe get this thing running soon.

Looks good! I can't help with the sway bar, I've never installed a rear one.

After months of distractions, I'm finally back to a spot where I want to get going on the Burb again. Since the last update, I managed to squeak the rear sway bar between the body and rails. I went back and forth a few times, but ultimately decided to sell the Wilwood Rear Disc kit with parking brake to a local C10 club member and purchase Captainfab's rear D52 brackets and new Wilwood D52 calipers. I just wasn't happy with the way my the parking brake kit matched the Wilwood D52 on the front, and I honestly can't remember the last time I used a parking brake in an auto tranny vehicle. I've also dove back into the wiring to figure out exactly where I'm at. With a little luck, I should have it running within the next few weeks. Thanks for hanging around!

Looking good! How did you go about painting the rails while still under the car?

On my back with a foam brush and a quart of POR15 and some
solid help from my apprentice. It wasn’t the most enjoyable part of the build so far.

Any man willing to risk getting POR15 on a clean Paw Patrol shirt is worth his weight in gold!

[04ls1gto]

He's hired! What sway bar did you use?

[shearjs]

I spent a little time installing the Captain Fab D52 brake brackets and new Wilwood rear calipers this weekend. These match the front brakes a lot better than my previous attempt. It also appears that the rear wheels are pushed out an additional 1/4” or so, which I desperately needed. I am not running the spacer pictured, just using it as a washer to hold the rotors right. The new studs were too long to use existing lugs without a spacer. 1 step closer!

Very nice work on your burb! This is all stuff I'd like to do to our burb eventually but the money tree is missing a lot of that green stuff.

Where did you get your tank at? LMC is OOS and every where else wants to sell you a Blazer tank. I am not into ordering something that won't really fit. If I'm going to modify something I'd rather put a larger capacity tank in it. Or, do the blazer tanks actually fit?

You might check out Boyd Welding....made in the USA and they offer a tank for the Suburban. Not cheap but very high quality, bolt in, and you can spec it with a number of options as far as return lines, baffles, pump assemblies, etc. Its the only company I've been able to find that offers a fabricated tank with the Suburban side fill.

I've got one of their tanks in my Longhorn. They do offer a very nice tank but a square body burb tank will be roughly $500 or more cheaper to get in and done.

I ordered a fuel tank kit for an 87-91 blazer through rockauto. It came with the tank, sending unit, fuel pump, and straps for $163. I swapped out the fuel pump with an Aeromotive 340lph. It is already baffled for fuel injection and only required moving the rear crossmember to make room. I'm pretty happy with the fitment. I had a Boyd tank on my old 70 GMC, but it felt like the 19 gallons didn't last very long with a 6.0L.

Jason, thanks for that. I also feel the 19gal isn't much. That is what my Boyd tank is. This burb will be going on some long trips so I might as well go bigger on capacity. $163 is a good price too!

I'm happy with the way it worked out. For the $, I feel like this was the best path to take for my project. I'll be happier when I know I have plenty of fuel pressure and get to hear this ol girl run again. It's been sitting around for far too long.
