KBS Coatings Cycle Tank Sealer Kit
The KBS Cycle Tank Sealer Kit is designed for sealing tanks up to 5 gallons. It includes KBS Klean, Rust Blast and Tank Sealer to permanently seal pinholes and weld seams. This kit supports restoration projects for older bikes or tanks with minor corrosion, enabling a reliable, sealed interior for gasoline storage. The compact all-in-one package helps simplify a sealing workflow and reduces the risk of fuel leaks after restoration.
TOFR Black 4.2 Gallon Gas Fuel Tank
The TOFR 4.2 gallon tank offers a larger capacity option for riders seeking extended range on Harley Sportster models. It is designed for compatibility with 2007–2022 Sportster XL variants and includes a tank cap. The larger capacity can reduce fuel stops on long rides and provide added flexibility for custom builds or touring setups.
EVIL ENERGY 5 Gallon Fuel Cell
The EVIL ENERGY 5 gallon aluminum fuel cell includes a built-in 3–90 ohm level sensor and anti-slosh foam. It is compatible with gasoline and diesel (not suitable for alcohol or ethanol blends), and its robust construction makes it suitable for street and drift applications. The level sender helps drivers monitor fuel without opening the tank, supporting better fuel management during longer sessions.
JSD AUTO PARTS 5 Gallon Tank
The JSD 5 gallon end-fill spun aluminum gas tank features a 3/8 NPT outlet with a vented cap and two black brackets included for mounting. Its design supports larger capacity applications and offers straightforward installation with mounting hardware. The robust aluminum construction can be an attractive option for custom builds seeking a larger fuel capacity with a lighter weight than steel alternatives.
SLMOTO 3.4/2.4 Gallon Universal Tank
The SLMOTO tank line includes a 3.4 gallon and 2.4 gallon capacity option designed for various Honda and compatible models. While not strictly five gallons, these tanks offer versatility for custom builds requiring larger capacity than stock but within a compact footprint. The 100% brand-new construction emphasizes durability and straightforward installation, with easy-fit mounting provisions and accessory compatibility.
Buying Guide: 5 Key Considerations For Your 5 Gallon Tank Upgrade
- Capacity versus motorcycle model: Five gallons is typical for adventure or touring setups, but some bikes may support slightly larger or smaller tanks. Confirm the tank’s fit with your frame and fuel system.
- Material and weight: Aluminum tanks are lighter than steel and resist corrosion, aiding handling and performance in long rides. Steel tanks are durable but heavier and can rust if not treated properly.
- Mounting and compatibility: Check mounting brackets, cap style, outlet fittings, and alignment with your handlebars and seat position. Retrofitting may require frame modification or additional hardware.
- Fuel system integration: Ensure the tank’s outlet size and venting match your carburetor or fuel-injection system. Consider adding a level sender for better fuel management if using a tank like EVIL ENERGY.
- Maintenance and sealing: If using a sealing kit like KBS Coatings, follow the instructions precisely to avoid leaks. Sealing is crucial for older tanks with pinholes or compromised welds.
This selection emphasizes options for extending range through larger-capacity tanks, enhanced fuel storage solutions, and restoration-ready sealing kits. Buyers should weigh compatibility, material choice, and installation effort when choosing the right option for their motorcycle and riding style.
