I have a 1987 Chevy 20 conversion van that the engine is blown in. It has almost a full tank of gas, that I'd like to siphon out and use in my other vehicles. It is not fuel injected, and I don't think it has a siphon block, but I'm not sure. What is the best way to do this? Is there a drain anywhere on the gas tank, or do I have to try to use a hose down the fill tube and suction?

 

How long has the gas been sitting in the tank. It may not be usable if it has been sitting for too long. You could try letting the fuel pump do the job. Disconnect the fuel line at the engine and run a hose from the line to a gas tank, then connect 12 volts to the fuel pump and let it do the work.

 

It's only been off the road a couple of months. It does still run at the moment, I've moved it a few feet here and there to mow the area.

I'm not sure about the fuel pump though. Does this year have an electric fuel pump, or a mechanical one? My 77 Impala has a mechanical one I know, but unsure of this year/model van.

 

If you have a Carburetor, it's likely to have a Mechanical Pump, which will be mounted on the side of the Engine.
If you are Injected, then it's going to be in the Fuel Tank and Electric.

 

This is a carbureted van, no fuel injection.

 

So, given I have a mechanical fuel pump, what's the best way to get the fuel out of this thing so I can use it elsewhere?

 

My 85 Blazer had a TBI injected engine with an electric fuel pump. It did look like it had a carburetor.

 

Mine is a 350 with a 4-barrel carb that I have to pump lots of times to start.
