Put the hose in your mouth and suck I don't think swallowing gas is worth it though

Its not that hard to syphon something.

If you have to ask how, I wouldnt reccommend that you do it by mouth, if you burn your lungs and die we dont need your family bitching at ls1tech for restitution.

Get an old inline fuel pump and prime the hoses and do it that way.

Newer vehicles are all equipped with an antisiphon device (big ping pong ball ) in the filler tube. Good luck getting a hose down the filler tube. I'd disconnect the fuel line from the fuel filter underneath. Pull the fuel pump relay and jump the contact, then run the tank dry....

Most vehicles have a fuel pump test wire (my LT1 does, anyway, right next to the PCM). Pop the fuel line at the fuel rail, put 12 volts on the test wire, and the pump starts spittin' gas. I use this to fill up my lawn mower (from my 94 Z28) all the time (since the 94Z runs on 87).

A cheap fuel pressure gauge (like the Actron one I got
at AutoZone) will have a Schrader fuel rail fitting
adaptor and a blow-off hose w/ button. So hook it up,
run the engine, blow gas out the hose until the fuel
gauge gets to "E".

Siphoning is what you do when you don't have tools
or keys.

Does anyone have a picture of where the test wire is? I think I am just missing it or maybe it is too late to be looking for this on a bad day.
