As I had to remove the front crossmember, I figured why not, let’s go ahead and pull the fuel tank out.
As the tank was about half full of that good old 1991 MTBE premium fuel that they had here in California, I figured I’d send it up to the shop that could boil it out and clean it up for me.
I removed all of the stone material, shot it with self etching primer, and then reapplied a fresh coat of Würth stone coating.
I don’t have any pictures of the fuel tank as it was installed in the car, but it was not gray in color, as I’ve seen other Porsches have. I don’t know if the previous owner at some point painted the fuel tank, which seems odd to me, or if it was painted at the factory.
