I own a '13 Accord and a '17 CRV and live in hurricane-prone Florida. During hurricane season (right around the corner), I keep my vehicles' tanks full incase we need to hit the road. I would like to siphon gas from one or both to fuel my generator when the power goes out. Once my gas cans run empty, I'd like to fill them from the cars and use the cans to refill the generator. I understand there are anti-siphon devices in newer vehicles - is there any way I could bypass them?
Put in a tube and see how far it goes. Pretty simple, if it comes out wet with gas then you can, if not then you can't.
If you're going to siphon gas, use a Mighty Vac or similar device to start the siphon.
I bet those of us old enough to know what a mouthful of gasoline tastes like are getting fewer and farther between
Amen, Brother!
yep! been there, done that! YUCK!
I have never tried this. So I really don’t know.
If you read on modern car gas tanks, there is a label that says, make sure to fuel within 30 minutes of opening the gas tank. Otherwise you won’t be able to fuel.
Maybe*** if you legitimately open the gas tank from the button in the car, you will be okay in siphoning. But if you pry the gas door open, the anti siphoning will be active.
Don't try to force a tube. The anti-rollover valve is likely plastic. Don't want any broken pieces sucked into the fuel pump.
Personally I wouldn't even consider siphoning gas from my tanks.
My suggestion would be to buy more gas cans in addition to the cans you already use. (that's what I do)
Do you have natural gas? You can run a generator on natural gas - or off propane tanks. The nice thing about running a generator off propane is that the fuel does not deteriorate like stored gasoline does.
With older cars you could disconnect the fuel line and jump the fuse to the fuel pump and pump it out that way. I don't know if you can do that with new cars though.
According to the 2001-2004 Ford Mustang service manual that I got, there is a way to siphon out the gas through the fill tube. It requires Ford Fuel Tank Drain Hose 310-F013. Near as I can tell, this is no longer available. There is a Ford Rotundra 310-102 Fuel Draining Hose and Adapter Kit that is similar but it's ridiculously expensive ($286). I wonder if it actually gets the job done and if it works on any on the newer vehicles. I haven't been successful siphoning gas out of my 02 Mustang or 14 Xterra using a 1/4 OD tube (1/8 ID). There should have been some kind of method to get the gas out without dropping the tank. I guess that's the way things go, fix one problem but create another.
In an emergency, If you really need to get gas from your car and there's no way to siphon it out through the fuel filler - you can remove the fuel pump from inside the car and get access to the fuel in the tank (But it's really not recommended)
I really don't recommend siphoning it out through the fuel filler, I once had fuel stolen and now my Toyota blows air from the fuel filler neck when I remove the cap and the fuel level reading is a bit unreliable (it's not a VSV fault, it's just a damaged fuel inlet valve)
I watched a youtube video where someone siphoned the gas out through the fuel filter with a hand pump. I kinda doubt that can be done since you would be trying to pull the gas out through the fuel pump. But if the fuel pump still works you should be able to get the gas out though the filter or fuel rail by applying continuous power to the fuel pump. The down side is that you might destroy the fuel pump this way. The fuel pump in my 02 Mustang recently died so I have to drop the tank with 11 gallons of gas in it. I wonder what method dealerships and independent service shops do in these situations.

I don’t think that there’s any need to drive the fuel pump on an Accord / CRV.
On Japanese cars you don’t need to drop the tank to access the fuel pump / tank internals.
on most Japanese cars, it’s just under the rear passengers’ seat - with it removed, you have access the tank internals.
In the case of the CRV, on most models it’s just under the 2nd row seats - meaning you don’t have to disassemble any interior pieces

on some old accords (although this probably isn’t OPs’ case) the fuel pump access hole was in the truck, near the spare tire - this means you don’t even have to remove the rear seat cushion.
Japanese cars are always so nice to work on compared to most European/ American.
