Fuel Fluke

For what it's worth, I had a fuel problem in my 67 ragtop Cuda which I bought after it had been sitting for years. I put in a new engine, fired it up and it ran for a day or so then stopped. The mechanical fuel pump quit pumping even thought it was brand new. I ordered another one, put it on and it lasted about another day or two. Finally I pulled the sending unit which I should have done from the start. The sock on the end was not even there and there was so much crap in the tank it was just sucking into the pump. Needless to say, I dropped the tank, dumped it, cleaned it and replaced the pickup tube/sending unit, sock etc. All is ok now that I have clean fuel. DUH!
