Shaker Siphon: Simply the Easiest Way NOT to Pour Fuel

Believe it or not, Dave and I have never filled either of our cruising boats at a fuel dock. Nope, every bit of fuel has gone into a jerry jug and then through a Baja filter* and into the tank.

And we jerry jug the gas for the dinghy. And until we got the watermaker recommissioned, we jerry-jugged our water. Now, our watermaker fills a jerry jug and we pour it into the water tank.

At roughly 40 pounds apiece, those 5 gallon jugs get heavy to hold up and pour in. But since we learned about these nifty little shaker siphons, we don’t pour them. And we don’t get fuel in our mouth starting the siphon, either. BONUS: They don’t spill like some of the “enviromental” spounts do!

DIY Tool: Five gallon fuel or water jogs get heavy to pour! Stop straining your back with these super-easy-to-use siphons.

The metal end is a check valve — the fluid can go into the tube through it, but not back through the valve. Start with the container you’re transferring from higher than where it’s going (the bigger the height difference, the faster the flow will be). Put the end with the check valve into the container you’re transferring from, the other end where you want it to go, and then jiggle the check-valve end up and down a few times (each time, more liquid will come into the tube) until it finally gets running downhill and the flow continues on its own.

Since it’s easier to show than explain, here’s Holly Scott of Charlie’s Charts:

This is one of those things that just makes life aboard so much easier. I’m amazed that everyone doesn’t already have one. I think Dave has given 4 or 5 of them to friends at our old lake house for fueling their boats, too!

Where to get your own? My number one choice is Charlie’s Charts since Holly went to the trouble of making a video to show how they work. You can also get them many other places, including Amazon. If you want to use one for both fuel and water, be sure to get two and label them both.

One final note: don’t try to use these to siphon gas out of a gas. Car gas tanks have some sort of anti-siphon device in them to defeat theives. They defeat owners, too.

*A Baja filter is a three-stage filter that gets out particles and water. Unfortunately, the original Baja filters are no longer being made. These Mr. Funnel filters are the closest thing I’ve been able to find.

    I used one of these this past Sunday. I couldn’t believe how well it worked. A bit slow, but no spillage whatsoever.

      I should have put that in the post — SO much better than the “environmental” spouts that leak everywhere!

    I discovered this really clever idea in Baja on a big 57 footer. It made topping off a breeze.

    No inexpensive that I buy these as gifts for other boaters. They always tell me it’s the best gift ever!

    Been using them for years. And the rate they pour works well with Baja filters.

    We have one for fuel and one for water from the Jerry cans into the tanks. Love them.

    We have fuel one and water one too and a spare I think. They are great. Wouldn’t be without them.

    I’ve thought about getting something like this for fuel. Where/how do you clean and/or store the siphon when not in use?

    • The Boat Galley

      We just wipe it off with a rag and put it in a Ziploc.

    It’s a good idea to wrap red tape on both ends of the one you use for fuel. It takes a long time to get the taste of fuel out of a water tank.

    Most NAPA stores in the U.S. Carry them as well.

    Do I understand it correctly that there is no good way of stopping it? I can’t fill a 1 gallon tank from a 5 gallon jerry can without a spill?

    • Carolyn Shearlock

      Sure you can slow it and stop it. To slow the flow, lift the container it’s flowing TO (or lower the one it’s coming FROM). The higher the “from” container is in relation to the “to” container, the faster the flow, so if you lessen the difference, the flow slows . . . and slows. And if the “to” container gets even an inch above the “from” container, the flow will stop. So pick up the container with one hand, and when the container is full and you’ve stopped the flow, pull the check valve end out of the “from” container and hold it up in the air to let what’s in the hose go into the “to” container. No spill. Wipe off the outside of the hose after using.

    i use these to fill my tractor in the field. You SHOULD bring a pair of nitrile/latex gloves with you because the hose will have petro poisons on it when you are done – AND a rag to wipe down the hose ends would be nice.

    Can you please tell Capt. Holly that the contact us email button does not work on her site? You just get an email that has no addressee in it. I want to ask her a question about purchasing this product.

      I sent her a Facebook message (I don’t have her email or I’d give it to you) and also gave her your email so hopefully she’ll contact you. She’s in California, so give her a few hours to be up!

    I’ve ordered a 2-pack of the shaker siphon through the links on this page. Thanks for the tip. I look forward to trying it.

    Have one that came with the boat for use with diesel . Works great and is easy to use. Take care though when getting close to a full tank, it’s easy to overfill. Don’t ask me how I know 😉

    One for water and one for fuel. Both well marked. Got them on a “two-fer” deal. Even John Mull likes them!
