Re: Repair of crack in Fuel Tank
I drove around for six years in an A100 Dodge van with a patch on the bottom
of the tank, but that was a metal tank patched with fiberglass body filler.
Fiberglass body filler is great stuff, by the way. I miss that van
sometimes. I think that it was the only vehicle I have ever gotten laid in.
There was that one other time I almost got laid in a Chevy station wagon in
the sixties, but I guess that doesn't count, because I was so drunk I fell
out of the car before I was able to consumate the encounter, but I
digress...
Anyway, I *think* that these tanks are polyethylene (polythene to our
British friends), and I *think* that in principle polyethylene can be welded
with heat. However, age and exposure to fuel are likely to make the
material more brittle and therefore make welding problematical. If it were
mine I would rough up the surface around the crack using a wire brush and
try to make a patch using silicon sealer, the good stuff.

Re: Repair of crack in Fuel Tank
Silicone will not work.
Silicone goes jelly in the presence of raw gas. Real fast too!
I tried to put a patch on my tank when I tossed it in the back torn
corner up with the filler tubes plugged with chunks of trees. I ran my
front diff vent line as a gas line extension up around and into the hole
and tried RTV to stop the splashes and smell. It went jelly. So did
duct tape so I just stuffed a plastic bag in the hole to slow down
splashing.

Re: Repair of crack in Fuel Tank
I think a lot depends on curing time and quality of the product. If you let
the stuff cure until it is as hard as it is going to get, and you use the
expensive stuff you might be all right.
