can I take filler end off gas line,to syphone out gas?

If you take the filler hose off at the tank with a full tank gas may come pouring out uncontrollably. Maybe try jacking up the other side of the car as high as you can. This should fill most of the filler neck up allowing you to siphon most of the gas out. After that you can more safely take the hose off if you feel you didnt get most of the gas out while the car was jacked up.

It depends on how much room the roll over valve gives you to sneak a hose in there to get the gas out, but taking the filler neck off will definately give you more room to work with.

Really, you're that desperate? Just add on the few $ for the full tank to the price of the car and stop being so petty because you'll just end up with a mouthful of "gas" vapour and be in pain.

for my section, the hot gas could be hydrogen for various motives a million) Its green - does not reason pollution. 2) The technologies has been obtainable for some years waiting to be faucet.3) develop information of the polluting outcomes of fossil gas 4) the fee of fossil has long gone way up for human beings to have sufficient funds it.5) gas cells that ability electric autos runs on hydrogen.6) inner combustion engines that oftentimes runs on gas on my own must be made to run on hydrogen or combination (hydrogen assisted gas gas combination) 7) As many have claimed, it must be use in deisel engines too. So old autos that runs on gas in basic terms must be switched over to run on hydrogen. So are we waiting for the tip of gas? properly i'm, I quite have a working hydrogen gas generator that in basic terms makes use of 0.5 ampere at 12 volts dc which I designed 30 years in the past.

just let the gas go with the car ! you can always buy gas for the next car.

sure but be ready to get soaked a bit if you can't take it off and put it on quick enough
