Last time on As the Tank Turns... We find that one of the 1970 FI T3 fuel tanks Big.Al is cleaning was built incorrectly. The return port was actually 3/4 covered by the internal cup. So Al's next step was to check out a tank from a 1969 FI to see how different it was and see if it would work. Russ was going to perform an autopsy on a rusty 1964 T34 gas tank to see if there was a cup in the pre-FI models. So, this weekend, I got the tank from the 1969 (68?) FI squareback from storage. It had the return pipe and a LOT of dust accumulation. ;) Similarities: the 1968-69 FI tank has the same footprint (mounting flange) as the 70. They also seems to have "almost" the same sheetmetal stamping and therefore presumably the same capacity. Fuel sensor mounting hole looks the same as does the return pipe and the supply port. Differences: The 68-69 tank has an oval-shaped filler port where the 1970 has a circular port. They are not the same diameter, so I either need to find a way to adapt the hose or replace the port with one from a 70. It also DOES NOT HAVE the tiny vent tube on the opposite side of the filler port. I can probably get around this by using a vented gas cap. However... NOW my problem is that some previous owner decided to cover up some internal tank rust by pouring in CLEAR EPOXY to try to stop the rust!!! This has evidently clogged up the area under the cup around the return pipe. :( I get a "little" trickle of gas through this area, but not nearly enough to be working properly. So, does anyone know of some chemical that might eat the epoxy, but NOT the metal? I guess I need to go find another tank from storage...
