Thread: Impala Fuel Tank leak

Tweet

Guys is their a fix for this, from underneath it looks like its leaking from the center of the tank

No!!!!!! You need a new tank.

Its just a slight leak that just started yesterday i guess. So they dont make anything to seal this

Yes, of course they do. But--its not something that you can add to the gasoline and fix it in place. You can take the tank off, try and figure out where the leak is, clean it up without blowing yourself up, put on any of a hundred different "sealing" compounds, put the tank back in----and 3 weeks later it will probably start leaking again. Gas tanks generally let go at the seam--and there is no way to fix that. Or else they rot out from the rust caused by condensation in the tank, and for every hole that rusts thru this month, there are 25 more just about rusted thru----after you find the leak and fix it, and reinstall the tank, they will break thru next month and start leaking again. Eastwood makes a gas tank "slosh compound" that you put in the tank and 'slosh" it around and then let it dry, then reinstall the tank. Then, 3 weeks from now you will put in a tank of gas that has some alcohol added at the refinery, and it will eat the "slosh" compound, and you will be right back where you started, with a leaky gas tank!!!! Been there!!! Did that!!! Two or three friggin times. Trust me. Get another tank!!!

Thanks i guess i hate to hear it but what can i do. I hope i dont have a hard time finding a tank its a 75 impala

Gas tanks are one of the things that were put on earth just to drive people crazy. When I was young and poor (which lasted about 45 years), it seemed that one of my cars always had a damn leaky tank, and I have tried just about every fix under the sun. I have never been succesfull at plugging a leaky gas tank. Now that I am old, and can afford a new car every 7 or 8 years, its not an issue, but man, I feel your pain!!!---Brian

I've been through it with a modified tank that was chopped to accommodate wheel tubs... cracked a seam and leaked , especially when particularly full... removed the tank, cleaned it out thoroughly at the local coin op car wash and got it welded... $200+ dollars later got it back in and it don't leak no more...

If I had the option, I would have definitely gone with a new replacement and even at that if I had to do it over again I would have gotten a fuel cell and mounted in the trunk for about the same cost as repairing the old one.

pin holes on the other hand... I would listen to Brian...

I used to repair gas tanks at the radiator shop I worked at.many radiator shops also repair gas tanks.they are boiled out with a caustic tanks (no boom boom) then the rust is ground away the area is then heated and cleaned with muratic acid and tinned and soldered like old school body work.depending on how bad the tank is most times the repaired area is much stronger than the rest of the tank.they should be able to tell you if its worth fixing .seen alot of time wasted by doit yourselfers trying to fix them

Sounds like it is leaking at the seam.......near impossible to repair.

Buy a new tank....they are cheap enough.

Nowadays gas is to high to have a leaky tank the premium is 3.96 in Atlanta and i need every drop of it

buy a new tank , or get on from a junk yard ..
