Re: Fuel tank
The tank I cleaned for a customer 10 years ago was dry, so I blew into it with an air compressor while sucking at the filler with a shop vac. This got rid of a lot of old dried gas and rust. Then I put 5 gallons of laquer thinner in the tank and drained it into a pail with a cloth on top to catch the junk. I did this several times while rocking the car back and forth. I had the drain cock removed and installed a fitting and hose for quicker draining. After this the tank was clean enough to install the pencil filter and drive it. Just have to clean the glass sediment bowl once in a while.
My Studebaker gas tank has some fine rust that finds it's way through the large gas filter and into the carb. I'm going to rig up my electric fuel pump to a couple hoses and large filter, and let it run for several hours to see if I can't get it cleaner. I can remove the sending unit and stick the hoses through that hole. I'll point them in opposite directions to make the gas circulate and hopefully pick up and carry out the fine junk.
