Today I removed the gas tank from my 56 Chevy. The sending unit was so badly corroded it was like a fossil. There was tons of loose stuff rattling around inside, including the pickup screen for the sending unit. I washed it out with water to get as much loose stuff out as I could. I also rattled a chain around in there for a while. Almost all of the loose stuff is now out. I'll go back at it tomorrw. I plan to clean it with muriatic acid, neutralize with baking soda and water, then use Red-Kote. As you may know from my earlier threads, the old gasoline in this truck really varnished up badly. I rebuilt the carb today after having the parts soaking in solvent for several days. I also pulled the manifolds because the intake was full of thick varnish like old maple syrup. I have that soaking now. I'm running all new fuel lines as well.
