My new gas tank strap insulator

[565bbchevy]

I bought this for my Regal since I will be installing a new gas tank even though it didn't come with any insulators I will use this rubber inner tube and when cut in half it will be 1-1/8" x 40"
for $6 it should work just fine.

Thanks for the idea. I'll probably use it myself.

The old time radiator guy in town (retired a few years ago) that fixed my 63 Olds fuel tank recommended roofing tar paper folded in half. I've done it on 3 vehicles; material was free from the neighbor.

I didn't use anything. If you get 'em good and tight then there will be no movement. No movement = no noise and no wear.

I bought some weird crap off eBay for the wagon (looks like rubber impregnated paper) and used some sheet rubber electrical taped to the strapa on the Monte (it was a quick fix given the "temporary" nature of the tank install). I made sure both tanks had protection on the top and bottom.

On a G body G47, I agree with using some tarpaper or water/wear resistant material to insulate the top of the tank from the body. Nothing on the bottom straps. Then tighten the straps tighter than Dlck's hat band. And then I'd send it.

If your straps are mangled up and don't fit flat against the tank, then perhaps using something might fill the gaps. But the key would be something with a harder durometer than bicycle tubes. It may over-compress and squish out or leave too much movement. Unless it's a temporary situation, I personally wouldn't use the tire tube. But it's not my car, so...

Cushioning is not necessary at all. Top supports or bottom straps. No positives.
Cushioning can lead to movement and movement leads to wear. No movement = no wear. Cushioning can also lead to more trapping of moisture leading to more corrosion.

I've seen it recommended for in tank fuel pumps to lessen the pump noise transmitting through to the body.

I agree. Don’t remember where I bought it but I bought the rubber insulators when I put a new tank in my 442. One of the reasons GM installed them was to reduce fuel pump noise

That Rubber may trap moisture which may lead to rust
