Re: 1929 gray powdery substance found in fuel

There is a possibility that the fuel that was in the tank had seasonal cleaning agents in it as well as the alcohol in it.

This same problem caused by 1940 carb on my Super 8 to have the same gray matter that made it thru my fuel filter and into the fine brass mesh of the carburetor. (Yes, it eventually caused my motor to run very rough.)

regarding reworking your tank: I cleaned and resealed my 1928 vacuum fuel pump about 4 years ago and have not have any issues with that junk getting into my fuel system. (takes just a few hours)


Best of luck.
