I need to siphon the old gas from the top of my tank. It's not coming out of the bottom, and I don't want gas everywhere.

Any tricks that don't involve sucking on the end of a hose and drinking gasoline?

If you have a Home Depot, or Loews nearby, they sell polyethylene syphon pumps for less than $5. They"re useful for everything from removing water to winterize toilets to syphoning gas. You simply give the bulb a few pumps to prime it, and off you go. Don"t last forever, but the price is right. I bought one for gasolene, one for kerosene, and one for my 5 gal can of Kroil penetrant.

Are you sure you have the shut-off valve open? Blow some air into the line and gas should run out. Sooner or later you will have to remove the sediment assy and there is no way you are going to be able to siphon all the gas out so you need to get the gas flowing thru the sediment assy.

I was told the reason the tractor stopped running was because the sealent had made it's way down out of the tank and clogged up the works.
The sediment bowl I have is a single line variety, and I want to put the starter tank back on it and run the line, even though I don't actually plan on using it, it's still a good conversation piece.

I had to get old gas out of my truck saddle tank which was above my gas can. I stuck one end of the hose in the bottom of my gas tank and used one of those little orange pumps on the other end. Once gas started to come out of the orange pump discharge end, I pulled the pump off of the hose and gas was comming out of the hose. It worked pretty slick! This got me wondering, How long of a hose can you use? I have trouble with 5 gallon cans so I was also wondering Can the discharge end of the hose be above the can being pumped out? thanks!!

I have used a compresser blow gun. Put the siphon hose in the tank and other end in a bucket.Then insert the tip of the blow gun just into the tank. Use a damp rag to seal around them both. Easy on the air blasts. David.

Used to keep the in-cab tank in my old Chevy company truck nearly full so I could draw gas for the generator, air compressor or any other gas equipment on the job. Beat heck out of hauling full gas cans to the site. Only had to haul diesel fuel cans.

Stuck a 1/2" diameter 6' hose in the fill neck and down into the tank, held a rag tightly around the hose/neck and just blew into the hose to briefly pressurize the tank, then quickly dropped the hose into the can. Couldn't do it with our newer pickups, as they all had frame-mounted tanks.

Someone once told my boss that I had a syphon hose in my truck and accused me of stealing company gas (had our own fuel tanks at the shop).
Didn't take long to explain why he seldom saw me pump any gas into a 5 gallon can, or why we never ran out of gas on any job I was at. ;O)

Takes forever to transfer fuel with one of them little hand syphon pumps, since they generally have small hoses on them.

Well, I gave it a try, but it doesn't look like there is enough gas in there to make this worth the effort. So, I am going to pull the tank and just dump the gas out.
by the way, old gas fumes don't taste so good. third party image

Use a clear 5/8 or 3/4 inch hose and use your thumb as a check valve.With the hose at the bottom of the tank,put your thumb over the end of the hose and pull up about a foot,then release your thumb and push the hose down to the bottom of the tank(fast).Repeat until the hose is almost full, then drain into a container.

Heres a trick a mechanic at the shop I work at showed me, if you have a air compressor and a air blower, blow air directly across the hose the is not stuck in the tank. this will create a vacumn in the hose, once the gas starts to flow, stop the air flow. and the gas will keep flowing.

Matt, My Dad showed me that trick, works great! Grandpa had a good one too, but when he saw Dad do that he shook his head. Grandpa had taken two pieces of copper tubing and solered them into a "Y" and would blow compressed air in the one side with the hose hooked to the other side. Grandpas deal looked great, but I don"t think he ever used it again!

Some of the better stocked truck stops sell a hose with a check valve on the end. Raise and lower the tank end rapidly and the hose will fill.

That's convenient, but if you are careful, you can siphon with your mouth and only get a small amount on your tongue.

Another way is to use a long hose. Ten or fifteen feet will do. One or two powerful sucks will start the siphon but won't fill your mouth.

If you have any doubts about your proficiency, practice with water or beer.

If your going to remove the tank anyway, just get someone to help lift off and dump gas out fill hole into a bucket. Have done that by myself before, but is easier with help.

Mike the little hand pumps that folks use for filling kerosene heaters work great. The plain hose also work fine and you just as well learn to do it now. The smaller diameter hose the easier it will siphon(sifer) I wouldnt try one over 1/2 inch by 5 feet long.

They make pumps that go on drills. They are under $20. That may be an even better/faster method.

I found out from a friend that using an electric drill powered pump is a bad idea. The problem is that electric drills (plug-in or cordless) are not explosion proof. His dad was using one of those pumps on his drill to empty the gas tank on his tractor when it caught on fire and badly burned him. Anytime you are using anything that sparks around gasoline you are asking for trouble. Roger

One esay way is buy a hose made for the older out board motors. Thye have a bulb on them that will primp the hose and then it will do the rest for you.

Here is the no mouth method:
with you hose of choice, put a plug in one end (cork, rubber, vinyl plastic)then fill the hose with gasoline from the other end.
With a full hose, hang the end with the cork in the container to be filled, as much lower as its length will allow. Rapidly put the open end into the liquid in the tank, and hold it there with tape or the like so it cannot get out, and is in the bottom. THen just uncork the bottom of the hose. If changing containers is needed, plug the bottom. Works much better than a mouth of (probably)leaded bad gasoline. JimN
By the way oil companies will take the old gas. look in the phone book.

Use a 1/4" or 5/6" hose and just give the a hose a slight suction and take your mouth away. You should then get a good stream of gas. Don't swallow any of the gas. Hal

Hal: Behind my farm used to be a maze of private logging roads. These could get you from one community to the next without going on public roads, thus they were used a bit by folks getting to a destination after being out tipping the bottle. One such trio landed in my door yard, on foot, late one Saturday night. Their pickup was 2 miles behind my place, out of gas. They wanted some gas, and had a designated driver, drinking but not much. I told them all I had was a barrel of gas with no pump in it, thus we would have to syphon. The owner of the truck, not the designated driver, decided since he was the one that started the evening without buying gas, he should be responcible for sucking on the hose. Looking back, we shouldn't have let him do the sucking. I don't know how much gas he consumed, however his buddies told me that 3 hours later at a hunting camp, every time he belched, all you could smell was gasoline.

When they came to the door, only the designated driver was able to get on my deck, one foot above ground level. Seeing the condition of his two buddies, I decided to drive them back to their truck. I figured the designated driver would have load enough with 5 gals. of gas, let alone keeping his companions mobile. These guys were on their way from a tractor pull and going to the hunting camp.

Hal: Good idea, and that reminds me of another one going back into the 30s, and days of an open fan for a defroster, and flip up windshield. Two guys coming from town, close to O degrees F, rubbing rum on the windshield the keep the frost off. Finally they opened the windshield, drank the rum and drove home.

I wonder if they made their own rum? Do to the bootleggers making their own alcohol is why they have the recipe for making ethanol. Hal

Yeah, get a transparent plastic hose, so you can see the fuel coming, 10 ft. long is good.

Janicolson has the best method. just make sure the end is below the tank at all times. I usally put a wire on the corked end and and several lead fishing weights on the open end and dip the whole tube in the gasoline and then pull the corked end out and quickly get it below the tank and open it up. A little patience will make it work.

Just give it a suck!

I can't remember the last time I got gas in my mouth while siphoning.

You give it a quick tug, not an extra long suck.
