Wevdn 2 PCS Gas Cans Racing Fuel Jug Hose & Cap 3042, 5 Gallon Racing Gas Tank Fuel Filler Hose with Jug Cap Replacement, Fuel Gas Can 3042 Utility Jug Cap with Fuel Jug Hose Bender

Refueling small engines should be uneventful. That’s exactly what I wanted from the Wevdn cap-and-hose kit—a simple, leak-free way to move fuel from a 5-gallon jug into motorcycles, mowers, and yard tools without wrestling with awkward spouts or splashy pours. After several weekends of use across two 3042-style utility jugs and a mix of small engines, here’s how it stacked up.

What you get and how it’s built

The kit I tested included a 3.9-inch replacement cap and a 13.4-inch flexible filler hose. The cap is molded plastic with broad, grippy knurling, and the hose has a pre-formed bend that helps you angle into awkward tank openings. There’s also a mesh screen integrated near the hose inlet—functioning as a debris filter—which is uncommon at this price point.

Materials-wise, both parts feel better than generic, no-name replacements. The cap resists flexing and didn’t show stress whitening when tightened firmly by hand. The hose is pliable without being gummy, holding its arc without kinking and returning to shape after being coiled. It’s clearly not a thin, single-use throwaway.

Setup and compatibility

This kit is designed as a 3042-style replacement for 5-gallon utility jugs. Threading is the sticking point with these systems: tolerances vary by jug brand and age, and caps that “fit” don’t always seal perfectly.

• On my newer jug, the cap threaded on cleanly and sealed with a firm hand-tight.
  
• On an older jug with slightly worn threads, I needed a single wrap of fuel-safe PTFE tape on the jug’s neck to stop a faint weep.

The cap’s gasket seated evenly in both cases. If you’re unsure about compatibility, measure your existing cap’s diameter and thread pitch and compare to the 3042 standard; it’s a quick way to avoid a mismatch.

Installation is straightforward:
1. Remove the original cap and spout.
2. Hand-tighten the Wevdn cap until the gasket compresses evenly.
3. Thread the hose onto the cap fitting and snug it down. Don’t wrench on it—overtightening plastic-to-plastic connections is a fast path to cracks.

Pro tip: A light swipe of silicone grease on the cap gasket helps it seat smoothly and reduces binding.

Performance: flow, control, and leaks

I judge a cap-and-hose setup on three things: how fast it flows, how well it lets me control the pour, and whether it keeps fuel off the floor and off my boots.

• Flow rate: With the jug vented, I could drain a 5-gallon jug in roughly 3–4 minutes through the hose—plenty fast for yard equipment, slower than a wide-open race jug. The integrated screen does temper flow a bit, but it also kept visible grit out of my motorcycle tank. If you need absolute maximum flow for pit stops, you’ll likely want a valve or a larger spout. For routine refueling, the rate felt sensible and predictable.

• Pour control: The pre-formed bend is the unsung hero here. It lets you set the hose in the tank opening and lift the jug with your dominant hand, without the hose trying to spring out. That made topping off small tanks—like a mower or generator—far less fiddly. I experienced minimal splashback because I could feather the angle easily.

• Leak management: On first assembly, I noticed a couple of damp spots at the hose-to-cap junction after the jug warmed in the sun and built pressure. A quarter-turn more by hand solved it on the newer jug; on the older jug, a wrap of PTFE tape eliminated the weep entirely. After that, no drips, even when the jug was laid on its side briefly in the truck bed. If you assemble dry and stop at “snug,” you might see small weeps. Take a minute to seat the gasket, tighten each junction firmly, and pressure-check with a small amount of fuel before real use.

Vent note: If your jug doesn’t have an effective vent, expect the hose to burble and occasionally belch; that’s not the kit’s fault. Venting made a big difference in smoothness.

Day-to-day usability

• Small-engine friendliness: The hose length is just right for getting into awkward filler necks without the jug needing to be too high. I liked it best for topping motorcycles on a stand and for refueling a generator tucked under a shelf.

• Clean handling: The cap texture is easy to grip with gloves. The hose resists flattening when pinched, but you can still “pinch off” flow in a pinch (pun intended). There’s no built-in shutoff or dry-break, so you’ll need to lift and rotate to stop flow cleanly.

• Filter maintenance: The integrated screen pops out for cleaning. It does what it’s supposed to—keeps junk out—at the cost of a little flow. I kept it in because the peace of mind outweighed the minor delay.

• Cold weather behavior: In an early morning test around 40°F, the hose stayed flexible enough to position without feeling brittle. That’s not always the case with bargain hoses that turn into PVC icicles when temperatures drop.

Build quality and durability

Over several weeks, the cap’s threads held up without rounding, and I saw no cracking or crazing around the hose fitting despite repeated tighten-loosen cycles. The gasket didn’t compress permanently or stick to the jug lip, which is a good sign of material quality.

That said, you do need to treat plastic threads with respect. Start them gently, and avoid using tools to “crank it down.” If a connection won’t seal with firm hand pressure and a clean gasket, address alignment or use a thin thread seal rather than brute force.

As for the hose, it shrugged off fuel exposure and didn’t cloud or stiffen. After a couple of long, hot afternoons in the truck, it still returned to its original arc. I did notice that fuel odor lingers if you store the hose attached; if you’re sensitive to smell, crack the cap to vent briefly after use and store the jug upright.

Value and package considerations

The option to buy a cap-only or a cap-plus-hose kit makes sense. If your hose is fine but the cap gasket is shot, replacing just the cap is smart. If your spout is cracked or kinked, get the full kit. I went with the two-piece kit so each jug had a dedicated setup. It arrived intact and properly packed in my case, and each component looked new—not scuffed or shelf-worn.

If you rely on a two-pack for a race weekend or worksite, check your package promptly and do a quick bench test with a splash of fuel or even water. That five-minute check can save you frustration later.

Who it’s for—and who it isn’t

Choose the Wevdn cap-and-hose kit if:
- You use 3042-style, 5-gallon utility jugs and want a straightforward, leak-resistant replacement.
- You value controlled pours into small tanks more than maximum dump speed.
- You want an integrated screen to keep debris out of carburetors and injectors.

Look elsewhere if:
- You need ultra-fast fueling for competition or large equipment and prefer wide-neck dump cans or dry-break systems.
- Your jug isn’t 3042-compatible or you’re tied to CARB-compliant spouts that require specific hardware.

Tips for a better experience

• Confirm 3042 compatibility and cap diameter (3.9 inches) before ordering.
  
• Lightly grease the gasket and hand-tighten until evenly compressed.
  
• Use a single wrap of fuel-safe PTFE tape if your jug threads are worn.
  
• Vent the jug to prevent burbling and speed up flow.
  
• Pressure-check with a small amount of fuel before throwing the setup in a vehicle.

Final take

The Wevdn cap-and-hose kit does the quiet work of fueling well. Once I snugged the connections properly and verified the seal, it delivered steady, controlled pours with minimal mess, and the materials have held up to regular use. The integrated screen trades a bit of speed for cleaner fuel—an exchange I’m happy to make for motorcycles and small engines.

Recommendation: I recommend this kit for anyone with 3042-style 5-gallon jugs who wants a reliable, easy-to-control spout for small engines. Be prepared to take two extra minutes on setup to ensure each joint is sealed, and you’ll be rewarded with a durable, low-drama fueling solution. If maximum flow or universal fit is your priority, you may want a different style, but for everyday refueling, this strikes a sensible balance of performance and value.
