Slant Six Bogging Down!

Well when I removed the fuel filter and found large deposits of rust and gunk. So I bought a new filter because I was not sure when it was last replaced. I then after a week of driving I pulled out the new filter to see if it had picked up anything and it turned out to look just as bad as the old filter that I had pulled. When I got to thinking about what could be in the tank I knew that the original owner of the vehicle was an elderly woman who had let the car sit for long periods of time in between driving. This causing oxidation in the tank #1. Also the gas gauge did not work which was either do to a rusted sending unit or a broken or dissolved float or both #2. So I decided to remove the tank and sending unit to see what was living in there and I found the sock around the pickup was clogged with junk that was in the tank. As I said in another post, I then went on and replaced both the sending unit and tank and have yet to have a problem.
