Poor fuel economy caused by.....
Well I've had poor fuel economy for a long time and could smell fuel every time I parked My car in the shed..
this is the reason....
When I took the tank off I didn't see any fuel leaking...
paint was over the top of the holes...
but I could see where there had been fuel leaking onto the chassis... so I took the fuel pipe and fitting off to see if it could be leaking... tried
adding rubber seals and refitting but fuel Was now leaking.. so tried all sorts of ways to try to stop the fuel leak... after a few tries... I started
to wonder if it really was leaking... and found the fuel coming from a different place... so, I wire brushed the bottom of the tank after taking the
fuel sender out and taking all the fuel out...
one hole appeared and then another.... I went to the local parts shop for a fuel tank repair kit and He sold Me a two pack epoxy kit [made inusa]...
I cleaned the inner holes and the outer holes [same holes really] with alcohol wipes.. then mixed the two pack epoxy and did the inside first.. on a
long screwdriver.. lol
then did the out surface.. sat it in the sun.. after an hour I gave it another coat on the outside and later another coat on the outside..
The holes were actually in the lowest part of the fuel tank..
[where water would collect...]
No More fuel smells and the fuel gauge seems stuck... 
and I took the tank out to replace the front end.... not to look for fuel leaks..

That stuff should be used for a temp repair only.
You need a new tank. If its holed in a couple of spots then more will appear.

I had a similar experience a months ago, could smell fuel, them one morning when it was really cold, I open the window so I could drive with my head
out coz my windscreen kept refreezing and I couldn't see for crap. I noticed the smell of fuel was like inhaling it as a liquid.
I stopped, but the difference was it wasn't my tank leaking but all my EFI lines were pissing out fuel like no tomorrow and my engine and tranny was
drenched in fuel and the bumper and boot and whole underbody was wet in fuel blowing under from the air stream.
I did a roadside repair, cut all my lines back and re clamped them all, got new hose when I got to work and changed them all at lunchtime . there was
nothing wrong with the hose just they were all squished out at the clamps and were too short once cut to really be used long term. They did pretty
good for 20 years.

Hi
I don't agree
its only where moisture of water has been sitting
and its at the lowest parts of the tank
I wire brushed it and found nothing more...
But My Son has a spare 69 tank so I'll get it wire brushed and see how it goes...
the two pack epoxy was called something like JK and was made in the USA..
actually a fellow in Canada told Me they have shops over there, that just repair fuel tanks...
the salt on the roads must eat them away over there...

I've known people to weld repairs on fuel tanks but you have to know what you're doing. POR15 do a repair epoxy paint that you pour into an empty
and dry tank. The epoxy will only last if it's petrol resistant.
Did you see any more dimples on the inside of the tank? They rust inside out so long as the outside paint hasn't been compromised.
Hope it lasts for you but glad you have a 2nd hand one if needed 
madness is in the eye of the beholder  |
