So i am trading my wife's car in, 2007 Trailblazer LT I-6, bought a 2012 malibu. She just filled the tank up yesterday with 70 bucks worth of gas and I really don't want to just GIVE the dealership all that premium goodness for free. Already tried shoving some 3/8 hose down the filler neck but something is keeping me from reaching the tank. Any way to use the fuel pump to "pump" out the gas. I know there filling up the new car but my truck is out and I'm thinking a free fill up would be nice lol any ideas are appreciated fellas
You may be able to disconnect the fuel line up by the engine, stick a piece of rubber tube on it, then jumper the fuel pump relay. Not sure how the fuel line connects on the newer vehicles though.
That's what I was thinking, just pop the line off at the intake and run a tube off of it into a bucket or if you get really ambitious, into the other gas tank. Then just jump the relay and let her pump dry.

I don't know about the NNBS, but on my NBS truck there is a spot next to the fuel pump relay that says "prime". Introducing 12V+ will kick on the fuel pump until the 12V is removed. I'd unhook it at the fuel filter if it's on the rail like mine is and fill you a couple of 5gal gas cans

You can use a fuel pressure gauge hose take off the gauge and fill up the gas canhook up to test port start and run truck and fill up you gas cans or get long enough hose and put straight into your tank
