Newb Question: Siphoning gas out of C3?
Anyone have any recommendations on the best, cheap way to siphon gas out of a C3 gas tank?
Just get a simple (really long) rubber hose that fits in the lid, then run the other end down to the ground? --How to start it? -I'm not going to go old-school and risk getting gas in my mouth. Note: I'm dropping the tank for putting in an 82" fuel hanger / sender unit and my EFI fuel pump if this opens up more options for me. Part of me wants to just leave the car running half backed out of the garage and wait for it to run out of fuel; there shouldn't be much in there and I'm getting rid of every inch of the existing fuel line, anyway...

i bought a kit for a few bucks that comes with a squeezable bulb and a one-way valve that starts the siphoning action.

Any thought on whether just letting the car run until it runs out of gas is a bad idea for any reason?
I'm thinking that it might even help reduce the amount of fuel left in the fuel lines when I go to pull them off, too.... Adam |
Hi Adam,
I believe you'll find that if you disconnect the supply and return lines at the fuel pump, the frame rail lines will drain forward. If you disconnect the supply line to the carburetor from the fuel pump the line will drain down. This will leave you with some gas on the fuel pump and some in the carburetor. Regards, Alan |
Bought a hand pump from the auto parts for $18, took the 2 yr old gas out of the Camino. Figured there was plenty left, it literally got all of it
Stuff would not fire period... Dont siphon :ack: |
Cheep hand pump @Harbor Freight or other hardware store works great, , no mater how long you run it, still will have some fuel lingering in lines and tank, but this will remove 99% of it, or drive it till on "E" then drop the tank, ,,, it could take longer than you expect to -idle it empty-:thumbs:

Regards, Alan I think I'll also listen to Cuisineart's recommendation of an $18 pump because I don't have a high confidence that just running the car out of gas will get everything that's in the tank. (If it had my Holley Fuel Mat in it already, I'd feel differently, I think.) Adam |
I've always used a squeeze bulb fuel primer for a Mercury Outboard motor that you can purchase from any marine/boat shop. Add a few feet of 3/8" fuel line on both ends and you can quickly remove all the fuel. I've had mine for years and they stand up better and last longer than the cheap plastic kits you can buy at any auto store. I've used mine over the years for my boats, lawn mowers, motorcycles and cars.

Another option that might work (never tried it) would be to use a handheld vacuum pump adapted to some 3/8" hose. Use the vacuum pump to suck the fuel up and out, getting it started, then disconnect it and let it flow. Last option, if the car is still on the road, is to just go out, drive it and enjoy it until you're down to nearly empty. If you have someone to help, you can take the tank out some (1-2 gallons) fuel left in it. Good luck with the swap. Someday I'll put either put this LS2 into my '71 or just convert it to FI - Not sure which way to go. Chris |
This one, under $20 emptied 15 gal pretty quick why do it the hard way

I just buy a length of clear PVC tubing from any hardware store and suck.
The clear tubing makes it easy to see where the fuel is and if it's long enough, you can run it from the tank to the ground and then up to standing height again so the chances of getting any in your mouth are slim to none. Just my .02 Elm |
Had some rubber plumbing stuff laying around- hose clamps - an air hose end and plastic electrical conduit elbow.
Disconnected the fuel line in the engine bay- Pressed it on the fuel cap opening- Hooked it up to my compressor and completely cleaned out the tank and the lines- DONE! https://cimg8.ibsrv.net/gimg/www.cor...273ede26f4.jpg |

What's car work without a mouthful of gas...oil...trans fluid...antifreeze...yada yada yada from time to time? I seem to be particularly fond of soaking my hair in trans fluid, I've done it at least 3 times in the last 6 months. And that OOOOOLLLLDDDD gas is best. That is some of the nastiest stuff I've ever had to deal with. Pour it on the ground and it sits there just like diesel, no evaporation, period. Wouldn't burn on a bet. I'm just too damn cheap to invest in any kind of a pump. I use hose and suck to start the siphon. The more I do it, the better I am able to time it and avoid the mouthful of gas. I just look at it as part of the job. |
Hi Adam. I've used one simple method all my adult life, just get an 8' length of 3/8" clear tubing at Oreillys. Run about three feet of it into the tank and standing up straight slowly suck fuel up to no more than a foot from the top. You can see it coming up, then quickly cap the end with your thumb. Now take the capped end down to your fuel container setting on the ground, and release your thumb. If the container is getting full, pick it up and allow the clear hose to get some air and it will break the siphon flow.
When you remove the hose use a finger to open the spring loaded flap and keep it from getting bent. A little gas on the tongue is the cost of a good education! |
i just use a "jiggler" hose,
even has a wire to earth out to stop sparks. https://cimg4.ibsrv.net/gimg/www.cor...777bd355d6.jpg |
Chassis manual has excellent instructions, use length of fuel line with 45 degrees slit cut near output end, use compressed air blower nozzle inserted in slit to begin siphoning. Simple, easy, reliable and inexpensive.

Simple.
I use a piece of that chrome metal tubing you see under your sinks, about a foot long, attached to a 5 or 6 ft long section of CLEAR vinyl tubing. Insert the metal tube into the tank locating it to the deepest spot in the tank. Position the other end of the vinyl hose close to the floor and , sorry, put it in your mouth and give it a suck. You can see when the gas is coming to avoid a mouthful of gas. |
