Moeller 25 Gallon Below Deck Tank
The Moeller 032525 Below Deck Permanent Fuel Tank is a 25 gallon aluminum tank designed for marine use. It features a machined aluminum 3/8 inch withdrawal fitting with a 360° swivel poplock for flexible hookup. The design emphasizes corrosion resistance with ethanol and biodiesel-compatible materials, helping to prevent pit formation and extending service life in fuel systems exposed to variable blends. It is suited for installation in tight engine bays or under-deck compartments where a reliable, secure fuel source is required.
Buyers Products SMC25AR Aluminum Reservoir
The Buyers Products SMC25AR is a 25 gallon aluminum hydraulic reservoir with dual rear 1 1/4 inch NPT return ports for clean routing, internal baffling to reduce sloshing, and a durable corrosion-resistant aluminum build. This tank is designed for hydraulic systems and other high-demand fluid storage applications, offering robust mounting brackets and a compact profile that integrates with typical vehicle or trailer setups. It provides a reliable fuel or fluid reservoir with minimized movement during operation.
EVIL ENERGY 19 Gallon Fuel Cell
The EVIL ENERGY 19 gallon fuel cell is an aluminum tank featuring a built-in 3–90 ohm level sensor and internal anti-slosh foam. Its dimensions are 29.5″ long by 12″ wide by 12″ high, with 8AN inlet/outlet fittings. While it isn’t a 25 gallon tank, its modular design and level sensing enhance monitoring for fuel storage in performance vehicles or small craft where compact, precise fuel management matters. It supports various fuels and blends but is not recommended for certain E85/ethanol blends when paired with specific fuel lines.
GSTP 17 Gallon Aluminum Fuel Cell
The GSTP Universal 17 gallon fuel cell tank offers a lightweight aluminum construction with a cap and level sender included. Its compact size (29.5″ L x 17.1″ W x 7.1″ H) makes it suitable for hot rods, street cars, trucks, and small marine setups where space is at a premium. While not a full 25 gallon option, it provides solid aluminum reliability and straightforward installation for growing or future expansion plans in a tight system.
15 Gallon Aluminum Fuel Cell Tank (RainMan S)
The 15 gallon aluminum fuel cell from RainMan S is designed for universal compatibility with hot rods, street racing, drift cars, trucks, and SUVs. It measures 29.5″ L x 7″ W x 17″ H, with a 15 gallon capacity and a 0-90 ohm fuel sender. It includes an 8 AN rollover vent and is constructed from high-quality aluminum for durability and straightforward installation. This option suits projects needing a lighter, smaller tank with dependable sensing capabilities.
Buying Guide
- Capacity and fit: For true 25 gallon needs, prioritize Moeller and Buyers Products options. If installation space is limited, consider smaller capacities with room to upgrade later or modular systems that support expansion.
- Material and corrosion resistance: Aluminum provides corrosion resistance and strength-to-weight benefits, especially when exposed to ethanol or biodiesel blends. Look for tanks with compatible fittings and anti-corrosion finishes.
- Fittings and compatibility: Check inlet/outlet sizes (e.g., 8AN) and whether the tank includes level senders or needs separate sensors. Ensure grommets, caps, and venting meet your system requirements.
- Mounting and support: Consider mounting brackets, internal baffles, and installation space. Tanks with integrated brackets simplify retrofits in boats or trailers.
- Safety and venting: Proper venting prevents vapor lock and pressure buildup. Include rollover vents or vent caps if required by your setup and environment.
- Cross-application flexibility: Some tanks are designed for marine use, others for automotive or racing applications. Ensure the tank’s design aligns with your primary use case and fluid type.
- Pricing and sourcing: Aluminum tanks can vary in price based on capacity, fittings, and brand. Evaluate total cost of ownership, including installation hardware and sensors, not just the tank price.
- Warranty and support: Look for manufacturer warranties and accessible customer support in case of defects, leaks, or compatibility questions.
- Future-proofing: If you anticipate upgrading capacity or adding sensors, choose tanks that support modular components and easy sensor integration.
