The Original Safety Siphon6 Foot Hose For Gasoline And More - 1/2" Valve Siphon Pump - Use for Cars, Boats, Mowers - Self Priming Pump Transfers 3.5 Gallons per Minute - FDA Food Grade for Home Brews

Just used this to transfer 5 gal can full of gas to my late-model car, worked fast and perfectly...didnt spill a single drop, and probably only left 1/4 cup or so in the can after I held it up at angle as it was getting near empty. I had worried that the plastic (vinyl, or whatever the material is) hose might not be stiff enough to force past the anti-siphon/roll-over flapper valve in the tank's "fill pipe", but it was no problem at all. Also had been worried that if the hose material was flimsy it would deteriorate after exposure to gas, but as thick as this material is I dont think that will be a problem. There is a video on Utube showing a guy sitting a 5 gal plastic can up on a car's trunk (towel underneath to prevent scratches) and that gave the siphon plenty enough elevation from can to car tank for a strong flow, and I can confirm as much cause thats exactly what I did. Didnt time the process but the flow started immediately and the tank was empty in surely less than 3 minutes. To get gas from a FULL or nearly full can into a car tank, there cant be a simpler, easier way to do it. Be advised the physics involved: you need to have enough depth of fluid that you are sticking the valve into to give you room for at least 5-6" (I'm guessing) of motion for you to keep the valve completely submerged; if you were to try to get it going in a partially filled can, you might not get the flow started, or at least not easily started.

What a simple device that can save you in a pinch. Really works well with gas cans and even down filler tubes is large enough. No leaks.

Works amazing. Just a little shake and it works great

hey it works as a self priming siphon.drop the brass end in and the hose lower than the can & give it a few up n down shakes to lift the fuelthat can be easily seen in the clear tube, as the fluid is over the high spot in the tube it flows out into the tank.EZ it was as ez as others said - so a nice surprise it works.I might get another with a short tube to fill the dozer tank. [4' should do nicely from my can]

Needed to get water out of my boat that pooled in my cover. At first, I thought it wasn’t working, but I just had to shake it like my life depended on it and the water started flowing. 10/10!

Love this syphon. The nozzles on the new red gas cans are impossible to use now, I needed something easy to empty the can. Put the copper end into the red can, move it up and down a few times to get the gas moving through the tube and just like that, it emptied in a few minutes! No mess, no frustration.Definitely recommend it!

This review is intended to those who transfer gasoline from CARB compliant gas cans. You are a frustrated group who has to manhandle 40 lb, 5-gallon cans of gas while trying to finesse the CARB nozzles to open up and allow the fill to happen. These new nozzles are intended to reduce hydrocarbon emissions but they do the opposite. The CARB nozzles are so hard to use and actually lead to more gasoline spillage than the old system. These el cheapo plastic nozzles are not intended to withstand 40 lb side load, which causes them to deform and leak. The rate of flow is excruciatingly slow, adding to the frustration.I often wondered why something so stupid remains in the market. Tree huggers who thought they had a win are screwed because the CARB compliant nozzles hurt the environment more.Aha, enter the Safety Siphon to save the day! To empty a 5-gallon can of gas into a vehicle, just place the can on a small step ladder (3’ high). Feed the PVC hose into the gas filler pipe deep so that its exit is below the liquid level in the gas can. Open up the gas can, insert the action end of the Safety Siphon and off you go! Once flow is established just watch it work. At some point in the transfer, the flow slows. Just pick up the can, which is much lighter to complete the transfer by increasing the elevation difference. At the end, tilting the tank allows almost complete emptying. When the flow stops, lift the action end of the Safety Siphon and drain the gasoline retained in the PVC tube into the vehicle.Such a simple device saves so much work and eliminates frustration.

I used this to empty my diesel fuel tank on my vehicle.It was down below 1/4 tank but I didn't want to remove the drain plug and have it go all over.At first it wasn't working, and I moved it around for quite a while and was frustrated.Then I re-read the instructions and realized that I was probably moving it out of the fuel when I was moving it up and down since the level was low.I tried again with smaller movements and it worked perfectly.I drained 22 gallons from my 80 gallon tank. It never lost suction, it just kept going and going.Will keep it around just in case.
