Gas tank install
« on: March 23, 2009, 12:01:33 PM »

Going to install the gas tank this week, if the "Honey Do" list isn't to full! Is there something that goes between the tank and body and between the straps and the tank? Some sort of cushioning or insulation?
 
Well maybe not putting in the tank this week!   I see the sending unit has had some "modifications" done by the speed shop who butchered the frame of the car. It's got a huge, looks like 5/8 inch, fuel line coming out of it. Some place I can send this to get it repaired or buy a new one? Can you still find sending units or do I go salvage yard hunting and hope I get one that works!

There's a rub pad that goes between the tank and the body.  I don't know if you can buy it after market or not.  Anything sturdy that won't fall apart and hold moisture will work.  It's the dimension of the top of the tank.
 
There is nothing between the straps and the tank.

I think you can get something similar to what the factory put between the tank and the floor of the car at a home improvement store.  It is very similar to roofing material afaik.

New C body sending units are available.
 Manufactured by Spectra Premium part # FG148A
Do some shopping around.Some places like to charge big bux for it.Average is 149.95.
The piece between the tank and trunk floor is like thick heavy tar paper.
I hope you have new J bolts.Old ones are usually stretched out.
Repop B body J bolts are cheap,plentiful and will fit.

Yup as Leaburn stated...I used the HEAVY felt for roofing as a pad before...think I doubled it up just for a little extra cushion.

Basically it is tar paper that isolates the tank from the trunk floor to keep the two from vibrating or rusting together. Undercoating would work, but then the tank would be stuck to the floor of the trunk, so don't do that.  Just don't use the tarpaper that has the rock on one side, but any 15lb paper or heavier will work just fine.

Under coating with a layer of Wax Paper will cure the sticking problem.  Or you can undercoat and cover it with aluminum foil.  Actually better

True, but undercoating can be messy, heavy tarpaper is easier to handle. As far as undercoating goes, I'm kind of liking that truck bedliner stuff. A whole lot better than the tar-based stuff in a can you spray on, and a whole lot easier to clean up afterwards.

The only thing I don't like about the bed liner is the cost and it gets too hard

Well, you don't have to use it all at once and I think you can get it in quarts, real good about sticking to metal, and although it gets hard, it is a flexible hard, so it really lasts a long time and prevents rust really well.
