Freeing Up An Engine That Has Been Sitting For a While

I agree with Bruzilla! My Roadrunner sat for 13 years, and the gas in the tank was putrid and full of rust as well as the tank itself and the pickup and the lines were all very rusty, and this was a car sitting in a garage for this long. I cant imagine the lines on that car are clean, since they are soft steel, they most likely are rusted internally, so if you are going to fire this engine, I would rig up and alternate fuel tank or canister to temporarily run it to see how she does, otherwise you are just going to introduce rust particles back into the fuel pump, filter and possibly the carb.

I would suggest saving yourself a lot of heartache and just replace the fuel tank, sender unit, and fuel pump now. Just draining the gas and putting in fresh isn't going to help.

The sender unit in my Roadrunner was so rusted through from sitting in a near empty tank for three years it looked like swiss cheese. How it was still moving gas I'll never know.

Thanks Bruz, that has been the plan all along. You forgot to mention radiator, the fuel lines and carb re-build.
When we get to the point that we're going to attempt to fire this thing it will at least have clean fuel, oil, fire and coolant flowing through it. If it stumbles, it's getting yanked for a 340 and we're not really out anything.
Not my first rodeo.
