Still Hauling Gas Cans Like You’re Living in a Time Before Wheels?
Your back’s killing you. Your hands reek of gas.
Your boat’s ready. The water’s calling.
All you wanna do is get out there and relax.
Instead, you’re stuck hauling heavy, 5-gallon gas cans, spilling fuel, and burning 30 minutes just to fill up.
And if you’re filling up at the marina?
They’re charging you extra for every single drop.
You know it sucks, but you’ve just accepted it.
What if you never had to deal with this again?
Let’s Compare:The Painful Old Way vs. The "Smart Ass" Way
The Painful Old Way
- Haul Heavy Cans – Carry, lift, and pour 5-gallon jugs like a caveman, multiple trips just to fill up.
- Messy & Inefficient – Spilled fuel, soaked hands, toxic fumes—and let’s not talk about the wasted gas.
- Slow & Frustrating – Manually pouring fuel drop by drop, hoping you don’t spill half of it.
The Smart Ass Way:
- Motorized & Hassle-Free – 750W brushless motor, off-road tires, and disc brakes let you transport fuel with zero effort—even uphill.
- 50-Gallon Capacity – Holds 10X more fuel than a gas can, meaning fewer trips, less hassle.
- Lightning-Fast Refueling – 15 gallons per minute pump (faster than most gas stations), gets you back on the water in under 5 minutes.
- Zero Spills, No Mess – Leak-proof design, auto-shutoff nozzle, DOT-approved tank—no more messy spills.
- Built Tough, Built in the USA – 4 years of refinement/testing, made with heavy-duty materials, backed by a 1-year warranty.
Let customers speak for us
from 14 reviewsVery well designed and high quality manufacturing

I really miss slogging my 30 gallon gas caddy around or paying Marina gas prices. This 50 gal "Fuel Mule" is effortless and saves me many trips to the gas station. We ski every morning April through early November so we consume a lot of gas. I gravity fed my gas caddy which took forever so now with the auto shutoff pump and self propelled Fuel Mule refueling is convenient and almost fun. The founder and inventor of the Fuel Mule, Jerry Hoffman, is fabulous to work with along with his team. What a well engineered product and we love supporting such creative and practical entrepreneurs.

After 10 years of wrestling Jerry cans, we invested in a Smart Ass FuelMule. A perfect solution, with great customer service and build quality that exceeded our expectation! Yes, this is an investment…but worth every penny.

Hello,
We purchased this to use in our aircraft hangar when needing to ‘top off’ our Piper Tri Pacer or PT22 Ryan. When we bought ours the aviation model was not available so we added a few modifications. We talked with Jerry and his team took our suggestions and an ‘aviation model’ was born!
It is excellent because it is small enough to maneuver inside a hangar without a tow vehicle. It is well built and extremely user friendly. We love it!
Do yourself a favor—-BUY one!

Build quality is impeccable, definitely made in USA! Plenty of torque and very maneuverable with a full load, had no issues getting it into and out of the truck with the ramps. Bye Bye Jerry's!

Found these guys while trolling the web trying to find a better solution for getting fuel to our clients toys in a more efficient manner. We ordered 3 units to start. Talking with the crew at smart a** was great! Order arrived in a few days. Starting showing off the new units and getting the buzz rolling around the lakes in East Texas. Can’t wait to get the units in action at our clients homes! Due West Property Management LLC.

I cannot stress how satisfied I am with our Fuel Mule! It is so much better than fueling up on the water. Thank You Smart Ass Products for this fantastic product!

I have had several 28 gallon gas caddies with hand crank delivery. With no gas docks on our lake, these were my only way to fill a 50 gallon boat and 2 wave runners. While better than hauling down gas cans individually, these gas caddies were a lot of work! When I saw the smart ass Fuel mule with its battery operated drive and fuel delivery system as well as a 50 gallon tank, I knew that that was a must have for our water toys.
I had many conversations with Dylon from Smart Ass products and he was fantastic! If I didn’t get him live, he called me back within minutes and also was responsive to my text messages, even on weekends! The product was delivered with expert care, the instructions were very clear and the Fuel Mule was ready to go immediately with no assembly required.
The Fuel Mule cuts down on the labor of wheeling the old gas caddy down to the lake and hand cranking the fuel out of the old gas caddies and makes filling our water toys a breeze. Having the motorized drive, makes it so effortless to get the Fuel Mule in and out of your pick up or trailer to fill/transport and getting from the garage down to the lake. You may look at the price and be concerned by it, but I can tell you that the convenience of having a motorized drive and fuel filling mechanism is well worth the cost compared to how I was filling everything before. My old hand crank gas caddies are a thing of the past.
Thank you Smart Ass for coming up with a truly ingenious product and thank you Dylon for all of your assistance in getting me my Fuel Mule!!

The Fuel Mule is a very well made gas cart that takes fuel down to my dock with ease. I have a unique situation where my gangway is 110’ and on a pretty good incline and I have had no problems getting up or down. Brakes work well going down and the motor pulls up the hill no problem. Well done!

Great product that solves a major weekend headache. No gas on the lake and hauling cans multiple times per weekend is no longer a problem. Less trips to the gas station and more time on the lake.
Shipping was fast and crating was perfect.

I lug gas cans for boat fuel year round, I thought the fuel mule would help a little with not having tons of trips from the truck to the dock. But it’s way more! Filling it up is so much better, it’s like filling a car instead of a bunch of tops, some leak, fixing seals etc. and just the headache. Then filling the boat without a siphon hose or holding cans, just stand there and pump! Life changing for my lifestyle as an athlete and coach! Love it!!!

Finally a product that holds its quality to the American made standard. We use ours in a commercial setting and the staff loves the new product vs our old manual fuel caddy. Very well designed, very intuitive, very well made. Excited to put a second one in our fleet to eliminate the rest of the original caddys.

Since acquiring the Fuel mule, not only do I enjoy going to the gas station it makes it easier! Before the mule I had 22 gas cans to fill and carry down to the dock. All you need is one fuel mule! Load it in the truck go to the gas station in 30 mins or less you’re fueled up and ready to shred! WORK SMARTER NIT HARDER!

Great product with great support. What my video and you will want one!
I have truly enjoyed this product and has saved me a lot of time in fueling my lawn products.

Frequently Asked Questions
1. Is it hard to load into a truck bed?

Darn near anything:
- Gasoline (including E10/E15)

A Message From The Founder
Hey there, I’m Jerry Hoffmann, founder of Smart Ass Products, and if you’re anything like me, you’re sick of dealing with the hassle of refueling your boat.
I’ve always been a problem solver. First in IT, then in race car parts, and now in boating—where I found myself lugging heavy gas cans to my dock, wasting time, spilling fuel, and overpaying at the marina.
So, in 2020, I built the first Smart Ass Fuel Mule—the only motorized gas caddy designed to take the pain out of fueling up. After three seasons of testing (and saving over $15,000 on fuel), I knew I had something special.
The Smart Ass Fuel Mule is now ready to revolutionize the way you fuel up.
This beast is built tough, made in the USA, and designed to make fueling effortless.
Thank you for joining us on this journey...Our mission is to bring smart, innovative solutions to life, making your boating experience more convenient and enjoyable.
We’re here to make your life easier, one Smart Ass solution at a time.
If you’re still hauling gas cans like it’s the Stone Age, it’s time to upgrade. Try the Smart Ass Fuel Mule and never look back.
