I removed the fuel tank to clean and repair it. Move the trunk's carpet (the left side is attached under the weatherstrip - move the carpet to the side and drape it over the left rear fender) then remove the hoses and the panel covering the tank. I siphoned out as much of the old fuel as I could. Disconnect the wiring to the pump & fuel level sender then remove the screws around the tank's perimeter and maneuver the tank out.

Here is the tank on a work table. The in-tank pump & fuel level sender has been removed and the opening covered with masking tape prior to painting.

There were a few pinholes in the bottom of the tank. I flushed out the old fuel and let the tank air out for a few days. Then I used some body solder to patch the holes. One can apply this product with a 'heat gun' on the high setting - no torch needed!.

I covered over the tank openings with duct tape, scraped off the remnants of undercoating then squeezed it into my blasting cabinet to blast away loose rust and old paint. Next I gave it two coats of Por 15.



Finally, I treated the interior of the tank with Por 15's Fuel Tank Sealer. That should preserve the tank for a good, long while.

Here is where the tank lives - under the floor in the trunk:

And the tank installed: (Blue masking tape covers the tank openings so I don't drop things inside.)

And the removable floor section re-installed:

Next I will install the sender/in-tank pump, the fuel lines and filler hose.

Finally I will re-install the carpeting (and cover up all the work done here...)
