Gas tank insulating rubber/mat material
 
I am in the process of replacing the fuel tank in my 1971 vert with a new tanks EFI unit. I need to source some type of rubber mat or material to use between the tank and trunk floor and on the straps so those don't rub new holes into the new tank. I'm assuming that this product is cut to go where the tank meets the braces running under the trunk floor.

I see that Ames has a fuel tank mat but am wondering if anyone has use this particular item; or used some other type of material; and how thick this pad/mat is. And if you found something else that you used that is less costly by all means I'm all ears.

i used what Ames sells and was happy with it.

PGlade at V8Buick.com makes these. I've used one and was pleased. Pretty reasonable.

Ive used tar paper in the past. No troubles.

Only factory GM strips for me.

On an original car I use them between body and tank. On non-originals (Hot Rods) I use them between body and tank as well as between tank and straps.

Totally forgot about this...one more thing to buy for my resto.

Thanks everyone I had one sourced already and the ebay vendor flaked on me, two times in a row that ebay vendors have flaked. Thanks gokitty, I msged that fellow and will see how his prices compare to the Ames price.

You're welcome! I hope he can take care of this for you. The BOP A bodies share similarities so maybe this will cross over.

I've bought two from him. They are great and are made like factory down to the the plastic coating on one side (IIRC). I thought the prices were very reasonable at the time but it's been at least 10 years ago.

Looks like I'll have to create an account on V8Buick.com...

I didn't think all cars got this insulation according to a past post. When I dropped my original tank from my 72 Lemans vert, there was no insulation between floor and tank, nor the straps. I then installed new tank with none. Was I wrong? With everything tight. It's hard to believe there would be any chaffing for a hole to develope.

My 71 GTO ( a Fremont build) never came with Insulation. When I dropped the tank the original build sheet was still there, so I’m sure the tank had never been down.

tjs72lemans 03-25-2021 08:56 PM

Thanks. That makes me feel better.

If the straps are tight, there is no movement. With no movement, there will be no wear. I think going without is better as using insulation will make it hold moisture in between for longer.

And you regularly drive your car in rainstorms?

I do it to my hot rods to keep rust, from the bare metal straps, from collecting and transferring onto the tank.

By the way, do you have moisture rotting out the roof of your house?

Why are your straps going to rust and why are you leaving them in bare metal?

The tank I pulled from my vert looked to be original although no build sheet so its possible that it was replaced at one time or another. The tank had developed several tiny pinholes on the bottom right where the strap was laying on the tank.
Now this car has been subjected to some weather in her day and has a lot of rust issues that I'm beginning to tackle. And while I live in a very dry state and do not foresee driving the car in any wet weather, the new straps feel a bit rough on the edges so I figured that having a buffer between the strap, floor and tank would be a good idea to add in a little insurance against any issues.

lamans71, Here is a 68-70 A-body tank with the factory insulation mat to give you an idea of how it was placed during assembly (Baltimore car).

Thank you Dennis, that is indeed very helpful to see how the factory did the job.
