Continuing from another thread, the 72 Pantera I am working has a 3/72 build date. I have already. pulled the drain plug. At first, the twisting action was torquing the sheet metal. I have seen this before in other projects, so did what I have done in the past - 3/8" impact. Worked perfectly and quickly, and out came 8 gallons of orange fluid that SMELLED like gasoline!! Anyway, I have not yet disposed of it and had planned on adding a couple gallons of gas and the rest in diesel fuel. (Disclaimer - that idea came from a Pantera supplier.) Once in there, check for leaks and after a couple days slosh it with a long paint stir stick, pump it out and drain the rest. Strain it as needed and repeat. Once what CAN be removed will be, then leave the cap open to air out. Once ready to fire up the engine, a few gallons of fresh gas would go in to see if the fuel pump is still good !! FWIW, when I pulled the plug on the tank, there was some sediment in it, but not a lot. Also planned it a transparent fuel filter in the first fuel line about 4-6" from the tank fitting so what is coming out can be seen. I would rather ruin a dozen of THOSE things than pull the power train out. Ultimately, the owner knows that the tank may be an issue and is resigned to whatever has to be done.
