Finished the fuel tank portion of the rear enclosure.

... and with the top bolted on. I went with a bolt on top cover so That I would have easy access to the pump and lines in the future.

I did have a bit of a problem. When I built the enclosure I fitted it to the car, then removed it for final welding. Checked it by re-installing and everything was fine. Cut out the top piece, drilled all the holes, and welded the nuts on the bottom. Re-fitted, everything was fine. Welded the enclosure in without the top so I could reach the areas I needed to weld, prepped, and painted all the bare metal and places the paint bubbled. Put the top on (some of you know where this is going already) and Voila! none of the holes matched up anymore. It distorted enough that I couldn't put the bolts in. I had to break out the carbide bit and grind out each hole so that the bolts would go in. Sometimes I ain't the sharpest spine on the cactus.

I did add an extra vent to the fuel inlet pipe to try and prevent premature cutoff of the fuel station pump when filling up. I plan to run this together with the tank vent, then both to a rollover valve mounted where the original valve was at. It was located well above the new enclosure on an inside trunk brace, then routed to a bulkhead fitting in the side floor of the trunk area. The vent at the tank (and my new fittings) are all 1/2 inch inside diameter tubing. I believe this should be sufficient as it was what the stock setup was using.

I will need to coat all the weld areas in seam sealer, and undercoat all the exposed parts underneath, when completely finished. High density foam will be used around the top flange to seal the top cover, an aluminum plate will replace the heavy steel one eventually. I had planned to cover the trunk area in carpet to match the interior when done so that it has a nice finished look to it.

Now on to the muffler enclosure directly behind this one. The metal plate at the back (the one with the ventilation holes in it) is only there as a heat shield to prevent heat transfer from the hot muffler to the fuel tank.
