Warren, I haven't had time to mess with it over the holidays. I will be considering both yours and Mat M's approach. I don't doubt there can still be a dirt issue with this car even though I thought I had fixed this. I also can't wait to update the ignition(pertronixs on order), to elimimate any possible ignition issues. I plan on removing the sending unit and inspecting it closely and then blowing air thru the supply lines. I think I will also inspect the "new" filter to see how it looks. The car still has points, wires with unknown history, autolite plugs-ordered NGKs, and original coil. So I still have things to eliminate in this process. I appreciate you updating us Warren and congrats on your success.
