I have an '03 TrailBlazer LT 4WD that's been sitting for about 4 years with a half tank of gas in it. I tried to siphon the gas out, but I can't get a siphon hose all the way into the tank from the fill port.

I saw a YouTube method where the guy disconnected the battery, then disconnected a fuel line in the engine compartment and attached his drain hose to that point. Then he pulled the Fuel Pump Relay and jumpered two of the contacts. When he reconnected the battery, the fuel pump runs and the gas comes out his drain hose. Disconnect the battery, and the pump stops.

Can anyone link to a photo of exactly where best to disconnect a fuel line and attach the drain hose, and also show which contacts to jumper under the Fuel Pump Relay? Thanks!

 

You could also disconnect the fuel hose if you can get to it from underneath the vehicle.

 

I've discovered a threaded fuel pressure test port right next to the fuel filter underneath, just behind the driver seat. That'll do it!
