How do you flush a gas tank out? Just bought a car that has been idle for 16 years. I dropped and drained the tank, what next to get the gummed up stuff out of it? Please advise. ALso, the engine ran when he stopped it, what do I need to get done to it? Completely rebuilt? Its a 350/300 engine. Thanks

16 years. Wow. Solvent could take a lot of the gum out but it might end up being a combination of rust and gum in the tank. Not knowing how the car was stored I'd figure as a minimum take the plugs out paying attention to their condition for rust and what not. Then if no rust on any plugs you are very lucky. Also as a minimum take the valve covers off and look for rust. If no rust then you should make a trip to Vegas being on a roll like that. If no rust under the valve covers and plugs I'd try redoing the oils, coolant, and other fluids. Make sure everything is tight then prime and flush with a super light oil to see what comes out and then go to 10W-30W or just 30W for a quick few minutes of running. Not sure of the weights actually. Whatever oil you end up using for running the engine I'd change it not long after with the filter.
Your brake lines, calipers and cylinder will probably have water in them from the silicone pulling in moisture. It normally has rust in the lines, master, calipers and cylinders. One good thing a complete brake job is easy.
I hope you don't have to tear it down but rebuilding it might be the best answer. The gaskets right now not knowing what a running engine is might give you trouble.

Squirt a few shots of Marvel Mystery Oil in each cylinder and change the oil and add what you want to run along with a bottle of EOS so that you cam can get lubed b/c I bet it is real dry.

Good luck with her, and I bet she will be fine! pdq67

PS., Might smoke a schosh at first, but once warmed up and cleaned up will be fine!! And don't rpm her until she warms up but rather just high enough to lube the cam...

My car had sat for 10 years when I bought it. It had not been prepped in any way for it's long nap, just parked. I checked the plugs for rust, changed the oil and filter, pulled the distributer and primed the oil pump/engine. Then I put the distributer back in and started the engine. It started right up. That was 24 years ago, the engine still hasn't had any major work done to it.
