Default Whats the best way to drain fuel tank?

I bought a 95 Caprice wagon thats been sitting for about 5-8 years, and the fuel tank is mostly full. Whats the easiest way to drain the Gas out without dropping the tank?

I'm tempted to go buy some small hose and use shop vac to get Siphon going, but is there a better/easier way? Years ago, I've bought some of those cheap siphon kits from hardware stores, and most of them are junk and never worked from day one.

Is there a way to drain it by using the fuel pump? I already pulled the fuel filter and ran the fuel pump as I cycled the Ignition, but that was a slow boat to China. Is there a way to run the pump steady maybe?

Thanks

I just have to say that this is a sure-fire way to cause an explosion. You would be pumping gasoline vapors through a sparking electric motor and then blowing them all around your garage. You really would be a deadman.

Look next to your AC accumulator - there's a little connector. Disconnect the fuel line like you said, aim it into a gas can, then put 12V on that connnector. Done.

Disconnect at the fuel filter and get a GOOD connection (no sparks) to run your voltage to the pump and let the pump do the work.

The LT1 tanks have baffles, you'll only get about half out with a siphon anyway. Trust me I know from experience and a few mouth fulls of 87 octane

Someone else would have been writing it though. You'd be filed under "Crispy Critters" over at the local Burn Treatment Center.


Do yourself a favor, Assuming you are dropping the tank as part of this project,go get a drain plug from NAPA, Advance Auto etc. They run about five bucks. Put in in. IF you ever drop the tank a second time, you'll be really happy you spend the five bucks. Mine's been out four or five times now. Easiest way to drain the tank when the System is inoperative.

OK, I'll say it, because this is as much of a set up line as I've seen on these boards: The easiest way to drain the gas is to stomp your foot to the floor!

I just went through this had a full tank of gas and a dead fuel pump. You can get about 5 gallons from the fill tube before the baffle stops you. After that if you jack the car up and disconnect the vent line beside the fill neck you can snake a line through there to the center of the tank. I was able to remove about 18 gallons this way and the tank came down very easy.
