[mlittlefair]

If youre wheeling with a poly tank, chances are youre going to hit and crack them.

I would say cleaning the metal tanks is better or buying new metal ones.

My 77 had a replacement poly side tank that was purchased at WH, I could not get it to stop leaking at the sending unit seal. Different sealers were used, torque sequences, etc. I finally gave up and replaced it with a metal tank...

Some old school Radiator shops still boil fuel tanks and can add sealers on the inside, you might try that... (But it can be the same price as a new tank when you get done)

I still have (gasp!) the original poly aux tank in mine as supplied by Ford in September, 1969 when my Bronco was built. With the factory skidplate under it, natch. I keep waiting for the thing to fail, which I suppose it will someday.

I guess I'm cheap enough that if your tanks aren't leaking I'd try cleaning them out before replacing them.

So, I have never done anything with gas tanks is there anything I need and can I do it myself to save some cash? Thank once again for all your help!

Re: poly gas tanks?

I would try the easy way and pull the tanks out and slosh them around with gas inside and see if any loose debis comes out.

Maybe the sending unit filter is torn letting debis go through the fuel lines. Also I would add a large see through filter so you can see what is coming out of the tank.

Mine sat for 15 years with the fuel cap off. All i did was rinse it out with gas and add another; 2 total, fuel filter. Ran great until I smashed it in size about 1 gallon
