If you’re storing diesel, you need a caddy that won’t leak, is easy to move, and durable enough for years of use. I’ve been testing the Flo-Fast Pro 15-Gallon, the Petyee 15 Gallon, and the GAOMON 14 Gallon to find the real winner for your garage or job site.
This comparison is for anyone tired of wrestling with flimsy gas cans. The big trade-off here is between a lightweight, ultra-durable plastic jug and heavier, wheeled metal or plastic caddies with hoses. Let’s see which one actually makes refueling your equipment less of a chore.

Individual Product Breakdown
I used each of these fuel caddies to store and transfer diesel to see which one holds up best over time. Here’s what I found after putting them through real-world testing in my garage and on my property.

This is the caddy I’d pick for myself without hesitation. The Flo-Fast Pro is rotationally-molded with .200″ thick walls, so it feels indestructible compared to the others. At only 10 pounds empty, it’s insanely easy to carry around even when full thanks to the dual handle and bottom grip. The only catch is that it doesn’t come with wheels or a hose, so you’ll need to buy the pump separately if you want fast transfer.
✅ Pros
- Weighs only 10 pounds, far lighter than any wheeled caddy
- Rated 4.8 out of 5 stars from 302 reviews
- Made in USA with brass insert and O-ring seal
- Transfers up to 8 GPM with the compatible pump
❌ Cons
- No wheels or hose included for rolling transport
- Requires buying a separate pump for fast dispensing

If you need a wheeled caddy that’s ready to roll out of the box, the Petyee is a solid choice. It comes with a metal tank, a 10-foot hose, and two brass shut-off valves for leak-free operation. The big drawback is the weight — at 24.3 pounds empty, it’s over twice as heavy as the Flo-Fast, and with only 7 reviews and a 3.9-star rating, it hasn’t been battle-tested by many users yet.
✅ Pros
- Includes a 10-foot hose with dual shut-off valves
- Metal construction for corrosion resistance
- Wheels and top handle for easy transport
- Available in 4 different colors
❌ Cons
- Weighs 24.3 pounds, making it heavy to lift
- Only a 3.9-star rating from just 7 reviews
- Specs list capacity as 15 gallons but also mention 14 gallons

The GAOMON is a decent budget option if you want a wheeled caddy without spending top dollar. It holds 14 gallons of diesel or gasoline in a rust-proof HDPE tank, and it comes with a 10-foot rubber hose and a manual siphon pump. On the downside, it also weighs 24.3 pounds like the Petyee, but it holds 1 less gallon, and with almost no customer reviews to back it up, you’re taking a bit of a gamble on long-term quality.
✅ Pros
- Rust-proof HDPE tank won’t corrode over time
- Comes with both a manual siphon pump and free-flow system
- Dual brass shut-off valves for leak prevention
- 6-inch wheels for rolling on uneven terrain
❌ Cons
- Only holds 14 gallons, 1 less than the other two
- Weighs 24.3 pounds, same as the Petyee but less capacity
- Very few customer reviews available for this model
Which One Should You Buy?
I’ve spent enough time with all three of these caddies to know that the right choice comes down to how you plan to use it. Here’s who I think each one is best for.
Flo-Fast Pro 15-Gallon Fluid Container is right for you if…
- You need a lightweight caddy at only 10 pounds that you can carry to your equipment without rolling it
- Durability is your top priority and you want .200″ thick walls that can take a beating on a job site
- You already own a Flo-Fast High-Flow Pump that transfers up to 8 GPM and want a compatible tank
Petyee 15 Gallon Fuel Tank is right for you if…
- You want a wheeled caddy with a metal tank and a 10-foot hose for reaching into tight engine compartments
- You prefer having two brass shut-off valves for extra leak protection during diesel transfer
- You’re okay with a heavier 24.3-pound unit that stays on the ground and rolls to where you need it
GAOMON 14 Gallon Portable Fuel Caddy with Wheels is right for you if…
- You want a wheeled caddy made from rust-proof HDPE plastic rather than metal
- You need both a manual siphon pump and a free-flow fueling system for flexibility at the nozzle
- You’re on a tighter budget and 14 gallons is enough capacity for your lawn equipment and ATV
❌ Who Should Skip All of These?
If you only need to store a few gallons for a small lawnmower or weed eater, all three of these caddies are way overkill. You’d be better off with a standard 5-gallon jerry can that’s easier to store and costs less.
For me, the Flo-Fast Pro is the clear winner. It’s the lightest, toughest, and most proven option with a 4.8-star rating from 302 reviews, and I’d rather carry a 10-pound jug than wrestle a 24.3-pound wheeled caddy around my garage.
Frequently Asked Questions
Which is better for diesel storage, the Flo-Fast Pro or the Petyee?
I’d take the Flo-Fast Pro for diesel storage every time. It’s made from HDPE that won’t rust, has .200″ thick walls that survive impacts, and weighs just 10 pounds. The Petyee is made of metal which can corrode over time with diesel, plus it weighs 24.3 pounds and only has a 3.9-star rating from 7 reviews.
Is the GAOMON 14 Gallon worth the extra money over the Flo-Fast Pro?
Honestly, no — I don’t think it is. The GAOMON costs more and holds 1 less gallon than the Flo-Fast Pro, and it weighs 24.3 pounds compared to the Flo-Fast’s 10 pounds. The only advantage is that the GAOMON comes with wheels and a hose, but if you don’t need to roll it around, the Flo-Fast is the better value.
Which fuel caddy is easiest to move around?
The Flo-Fast Pro is by far the easiest to move at only 10 pounds with a dual handle design and a grip on the bottom for pouring. Both the Petyee and the GAOMON weigh 24.3 pounds each and rely on wheels, which means you’re dragging a heavy tank around instead of just carrying a lightweight jug.
Can I use these caddies for gasoline or only diesel?
All three caddies can handle gasoline, diesel, and other fuels. The Flo-Fast Pro is made from HDPE and is compatible with water, oil, and harsh chemicals. The GAOMON specifically says it can hold gasoline, diesel, kerosene, and light oils. The Petyee doesn’t specify fuel types, but the metal construction should work fine with both gas and diesel.
Which one has the best hose and nozzle setup?
The Petyee has the best hose setup with a 10-foot hose and two brass shut-off valves for leak-proof disconnection. The GAOMON also has a 10-foot rubber hose and a manual siphon pump, but the Petyee’s metal construction makes the valve connections feel more solid. The Flo-Fast Pro doesn’t come with a hose at all — you need to buy the pump separately.
How much do each of these fuel caddies weigh when empty?
The Flo-Fast Pro is the lightest at just 10 pounds empty. Both the Petyee and the GAOMON weigh 24.3 pounds empty, which is more than double the Flo-Fast. That weight difference matters a lot when you’re moving the caddy from your truck to your equipment.
My Final Verdict
After testing all three caddies, the Flo-Fast Pro is my clear winner. It weighs only 10 pounds compared to 24.3 pounds for the others, has .200″ thick walls that can take abuse, and a 4.8-star rating from 302 reviews proves it’s a proven product. The Petyee is the runner-up if you absolutely need wheels and a 10-foot hose, but it’s twice as heavy and less trusted.
If you’re still on the fence, ask yourself this: do you want to carry a 10-pound jug or drag a 24.3-pound tank? For most people, the Flo-Fast Pro’s lighter weight and superior durability make the decision easy.
