Siphoning Gas From a Car


Recommended Posts

Related to the portable generator question, I have another that you wrenches out there may know something about. Is it possible to siphon gas (for the generator) from a modern car?

I've done it..., 

 

You need a smallish hose, though.  A fat 1" garden hose isn't going to get past the restricted opening that is sized for pump nozzles.

 

I have a worn-out cheap 1/2 inch garden hose that I cut a 6 foot hose section out of.  It had a small enough outside diameter (O.D.) to get past the restriction.

Yes, I guess for how long depends on what it's made of.

But I can tell you you'll be missing out on that sweet sweet gasoline taste lol

Your hose probably hit a plastic anti siphon ball at the bottom of the filler tube. it can be pushed out of the way but takes a very stiff hose.

I don't see why adding an inline tee after the fuel pump wouldn't work. Add a ball valve after the tee on the engine side and a plug on the auxiliary port of the tee.

 

Close the valve to the engine, remove the plug, thread in a hose to fill your container and turn the engine over until your container is full.

Pop your fuel pump fuse out and start the car to release the pressure and when the car stalls unhook the line and connect a hose to it and into the gas can. Crank it over with a strong battery. Although you might burn up your starter, you can get your gas that way. xD

I have used an inexpensive electric fuel pump and some rubber gas line stuffed down the fill spout, which seems to work well too...  it takes a few minutes to pump a couple gallons.

Thank you. It tried but the siphon tube hits an obstruction about 20" in.  I remember easily siphoning gas for our lawn mower, chain saw, etc. in the past. Maybe now there is some new device installed because of emissions or something. Damn. Just want a source of gas for my portable generator so that I don't need to resort to storing gas cans.
