Description:

Selling a fully restored RX-7 FC S4 (86-88) fuel tank. 
 The tank was restored by Moyer Fuel Tank Renu in Greensburg, PA. You can take a look at their Google reviews and website to get an understanding of their process, but to briefly explain it they: 
 Cut the tank open. Sandblast the inside and outside completely to ensure a rust-free surface. Weld it back together. Do two rounds of applying and baking-on the Renu coating. 
 The final picture I uploaded shows the “BEFORE” of what this gas tank looked like. The reason why I’m selling it - I actually had the process done to TWO tanks I own. Long story short, my original FC tank was fairly rusty, I tried and failed to remove the all of the rust with electrolysis. I bought a junkyard one that had just a little surface rust, and tried to remove the surface rust with vinegar (as seen in the final picture). I repeatedly was getting flash rust while doing this, and so I gave up on trying to DIY, and brought both tanks to a professional. 
 You are getting the tank in the picture, except now it is fully rust-free and protected. I am just showing you the “before” so you get an understanding that the tank you are getting only had surface rust, and is now totally revamped. 
 I trust their process way more than any home method, such as POR15 or Red Kote, due to the sandblasting, and double-bake of the sealant. This is why I took both of my fuel tanks to them, and have confidence installing my original one back into my car. 
 I hope this tank can save you some $$ over buying a “new” one from Atkins or Mazdatrix for $800-$1000, plus the vapor valve + tank straps which are roughly another $100.
 I’d prefer to do local pickup, because the shipping costs are unfortunately very high. I’m willing to drive 1-2 hours to meet you. I’m located in the Pittsburgh, PA area. 
 If you prefer it to be shipped, the shipping costs will be $225.
