914World.com _ 914World Garage _ How did you paint/finish your gas tank?
Posted by: Tdskip Sep 22 2020, 07:57 AM
I pulled the fuel tank out of the Fresno 914 because it sat for 20+ years, and I’m not sure if it was properly drain first or if the fuel just all evaporated. Seems like a bad idea to just dump gas in it so it’s at a radiator shop being tested and cleaned out.
That, however, leaves me without a fuel tank to get the car fired up and I happen to have one that was dipped but is unfinished. Since the tanks are identical and not stamped I can swap them out without the car sliding into the “non-numbers matching “category. Doesn’t really matter because it’s a bit of this and get to that car since I bought it as a roller anyway. Ha.
So-how do you guys like to finish and recommend repairing the fuel tank. It looks like the tanks were originally just painted and assembled into the car without any interior lining to the tank, correct? Do the same thing or do you recommend getting them finished differently?
Thanks!

I've never had good luck with gas tank coatings (in 90's-early 2000's) so I just keep mine full with real gas.
But I can still get gas without ethanol, if I had to run E10 I'd likely look at coatings again.

Ended up bringing the tank to a local radiator shop. $240 coated and painted out the door, a lot more than buying a PO15 kit but saves time.

I used the Eastwood tank sealer and etcher. The sealer dries as hard as a rock and is reputed to seal small holes also. Once you coat the inside of your tank with the sealer, you drain the excess. I put some of the excess into an old coffee can as a test. If the coffee can is any indication, my gas tank is going to be just fine.

I’ve used the POR stuff as well, it held up, expect the Eastwood stuff will too.

When I first got back into AirCooled I picked up a 70 Ghia. Tank wound up being pretty toasty.
Por 15 and some fiberglass sealed it right up.
THE MESSIEST JOB I EVER ATTEMPTED. People thought I had contracted some skin disease.
If I do again I will get a full throw away coverall.

Fiberglass to seal up a fuel tank? No thank you.

Powder coat the outside. No coating inside. They did not have any coating from the factory.

Wow - that seems like a deal.
Would have been cheaper to just do that.
Anyone use one?

I had mine fine a few years ago at a radiator shop using this process.

It has held up exceptionally well.
But yes, this was before the repro tanks were available. I would have definitely done that if it were an option at the time. Once all the other stuff is placed on top of the tank it would be pretty tough to tell if it was original or aftermarket.
And yes, if you can get ethanol free fuel your entire fuel system will thank you. That garbage exists solely as a subsidy to the farm industry.
