You can't siphon a trucks gas just because it has a blue line flag. Most modern cars have an anti-siphon valve, so that causes issues.

Instead, you locate the fuel tank and drill a small hole in it. That way you can let the fuel collect in a tub or jug. On lifted trucks this is even easier. Drill the hole, pop a large jug under it, perhaps use a small rubber hose or funnel.

Remember to leave them a little note that you've drilled a hole, so they can go get it repaired and not leak fuel everywhere attempting to refill it.

Install a self-tapping valve, then you can drain the next tankfull even easier.

With this approach it’s best to not leave them a note.

Self tappers are great. Don't forget your gasket so they don't notice a drip.

Is that why I couldn't siphon my gas that I needed for a generator after a hurricane? Not only did I fail at what I thought would be an easy task, I got sick and threw up in my 95⁰ house

Pro tip for sucking volatile gases, you can suck air into your mouth and push it out your nose without it going into your lungs. I do that when I clean glass pieces with iso when there's still some vapors present. If you exhale out your nose while you do this you can be extra sure none goes into your lungs. Granted you should also be sure you're actually pulling liquid if you're trying to syphon, but at least you wouldn't be pulling into your lungs.

Haha yeah that was my method. I was just too stubborn and, combined with the heat at the time, courting disaster.

Yup, you got a lung full of gasoline vapors and nothing else. You need a car siphon pump, they're super cheap and available at any auto store. You just gotta make sure it's got a long hose on both sides and a tube for air to get into the tank. If the hose is too long just cut it. Those stick ones don't work on every car cause some gas tanks have slight bends.

Just shove tampons down the filler tube or any non fuel liquid

May as well take that cat converter while you're down there, for good luck.

bleach will oxidize the entire engine and seize it after several miles. No turning back from bleach.

Raw eggs and water in the gas tank takes less work, although you don't get gas out of it.

Just hope you don't make a spark while drilling

[–] Hyperreality@kbin.social 4 points 2 years ago* (last edited 2 years ago)

That's the good thing. AFAIK most tanks are plastic nowadays.

Good manners can't be left out , indeed.
