AloneGoer 3 Gallon Portable Boat Fuel Tank
Capacity and purpose: 12L (3 gallons) designed for outboard motors, inflatable boats, or as a spare fuel tank. The multi-layer barrier (HDPE-EVOH-HDPE) reduces fuel molecule permeation and evaporation by up to 98% compared with standard tanks. UV stabilization and salt spray resistance support longevity in harsh marine conditions. Best for: small jon boats or as a reliable spare that minimizes vapor loss. Caution: ensure proper hose alignment to prevent leaks during re-fueling.
Scepter 6 Gallon Portable Marine Gas Can
Capacity and features: 6 gallons (22.7 L) with 2-way vented cap that allows air flow during refueling and relieves pressure above 5 PSI, preventing vapor buildup. Built-in fuel gauge and a simple pickup system make fuel checks straightforward. Best for: boats needing longer fuel runs without frequent refills. Limitation: tank does not include a hose; buy separately if needed for your setup.
VEVOR Marine Tank, 6.34-Gallon
Capacity and build: 6.34 gallons (24 L) with a 9.8 ft hose and a separate inlet/outlet to minimize spills. Constructed from HDPE with a visible gauge for quick checks. Best for: mid-size boats needing dependable fuel storage with a built-in gauge. Caution: avoid prolonged direct sunlight exposure to prevent aging and expansion.
VEVOR Boat Fuel Tank, 3.17-Gallon
Capacity and compatibility: 3.17 gallons (12 L) with a 9.8 ft hose, compatible with Yamaha connectors. Built from high-density polyethylene for durability and resistance to aging and impact. Best for: smaller outboard setups or as a compact backup tank. Limitation: ensure proper hose fitment to Yamaha connectors to avoid leaks.
Attwood 8803LP2 3-Gallon Portable Tank
Construction and flow: automotive-grade multi-layer construction for durability in extreme environments. Features an automatic vacuum valve for steady fuel flow without manual venting. Best for: users needing a robust, reliable tank that performs under heavy use and varied temperatures. Caution: ensure compatibility with existing fittings and hoses to maintain a leak-free system.
Portable Boat Fuel Gas Tank, 3 Gallon/12L
Design and features: 3 gallons with ergonomic I-shaped handle, clear fuel gauge, and built-in filter. Best for: anglers or recreational boaters who prioritize easy handling and onboard visibility of fuel state. Limitation: smaller capacity may require more frequent refueling on longer trips.
Buying Guide: How To Choose The Right Jon Boat Gas Tank
What capacity suits your boating style? If you run longer trips or heavier use, consider 6–12 gallon tanks. For casual weekend outings or as a spare, 3–4 gallon tanks are often sufficient.
Do you need a built-in gauge? Tanks with a visible gauge simplify monitoring fuel levels, reducing anxious guessing on the water.
Hose length and fittings matter. Confirm that the hose length (usually 9.8 ft) fits your boat layout and that connectors match your outboard’s intake.
Durability and environmental resistance. Tanks made from HDPE with EVOH barriers offer better durability and lower evaporation, especially in salt spray or humid climates.
Ventilation and vent specs. Vented caps help manage pressure during refueling, but ensure ventilation complies with local regulations and boat storage practices.
Portability and storage. If space is tight, under-seat-friendly designs or compact footprints help, especially on smaller jon boats.
FAQ
- Q: Which gas tank capacity is best for a small jon boat?
- A: For limited space and moderate usage, 3 to 6 gallons is often optimal; larger tanks are for longer trips or higher fuel needs.
- Q: Do these tanks support ethanol or diesel?
- A: Some tanks are designed to be compatible with ethanol-blended fuels; verify the model’s compatibility before use.
- Q: Is a built-in fuel gauge essential?
- A: A gauge helps with quick checks and planning, especially for boats with limited storage or mid-range trips.
- Q: Are there safety considerations for marine fuel tanks?
- A: Yes. Use properly rated hoses, secure tanks to prevent movement, avoid direct sunlight when possible, and follow local storage regulations.
- Q: Can I use any tank under the seat?
- A: Check that the tank’s dimensions fit your under-seat space and that mounting is secure to prevent shifting during operation.
