![Question](https://rennlist.com/forums/images/icons/icon5.gif)
I'm in the process of restoring my '67S and recently took a look at the fuel tank that was pulled out. Ouch, was it ugly - lots of rust and corrosion. Replacing it is out of the question for now ($750+).
I'd like to tackle the project of sealing it myself but dont really have a clue as to where to begin (chemicals to be used , etc..) Is the cost and time worth it? or should I just send it out to an expert and pay the $? Any feedback or links would be great.
Thanks,
Scott

Hi Scott:
That Sir, is a hazardous and potentially dangerous job, BTDT.
I would advise you to look through Hemming's and perhaps find someone close to you that has experience with these and can do this properly.
The Eastwood Company makes several DIY'er products for this but this one job for a pro.
Caveat Emptor, if you tackle that yourself.

POR15 has some information and products on it's web site. FAQ on fuel tank renewal at <a href="http://www.por15.com/faqs/faqtanks.html." target="_blank">http://www.por15.com/faqs/faqtanks.html.</a> (No affiliation beyond using some of their paints and muffler sealer products, and do recommend those.)

I have done this just 4 months ago...it was not that hard once it was all said and done. I ordered the POR15 fuel tank sealer kit, and a large bottle of naval jelly.
1. Disconnect battery!!!
2. Drain the fuel from the tank (should be low to start with)
3. Disconnect the fuel lines from the back of the tank.
4. Disconnect the fill hose and overflow hose.
5. Disconnect the sending unit, and remove it.
6. Make sure to remove the drain plug and filter!
7. Remove tank, three bolts.
8. Take the tank to a car wash a rinse the tank. Let dry.
9. Plug all the holes with whatever you can, I cut small plastic plugs and forced them into the holed.
10. Pour in the naval jelly and rotate the tank for coverage...follow instructions on bottle.
11. Rinse, Rinse, Rinse, let dry.
12. Use the POR15 metal etcher.
13. Rinse, Rinse, Rinse, let dry.
14. Pour in the POR15 and rotate the tank for coverage...do this for an hour, let the tank sit on each side for several minutes to allow coverage.
15. Drain the POR15...this takes several hours!
16. Let it dry...96 hours!!!
17. Make sure the holes in the tank are open a clear.
18. Replace the drain plug and filter.
19. Install sending unit.
20. Install tank, connect hoses, and bolt it down.
21. Fill with appx 5 gal of fuel to purge lines.
22. Connect battery.
23. Start it up!
I have not had any problems since.
CONSIDER: Replace fuel filter and fuel pump...it's probably rusty all through the system.
