GSTP Universal 15 Gallon Fuel Cell Tank
The GSTP 15 Gallon fuel cell is designed for broad vehicle compatibility, including hot rods, street cars, trucks, and SUVs, with marine adaptation potential. It features anti-sloshing foam to stabilize fuel in motion and a polished aluminum finish that resists corrosion. Best for lightweight builds or racers who need a compact tank with reliable fuel delivery. A potential limitation is the smaller capacity for longer journeys unless multiple tanks are used.
Parts-Diyer 14-15 Gallon Aluminum Fuel Cell Tank (Blue)
This 15-gallon Parts-Diyer tank measures about 30″ L x 12″ W x 9″ H and includes a 0-90 Ohm fuel sender with an 8 AN rollover vent. Made of high-quality aluminum, it offers light weight, durability, and ease of cleaning. It’s well suited for street drift, racing, and pontoon setups where a robust, mid-range capacity is needed. Better for users prioritizing a built-in level sensor and straightforward top-vent design; however, some installations may require precise mounting to fit within limited bilge space.
GSTP 20 Gallon Fuel Cell with Cap Level Sender
This GSTP fuel cell provides larger capacity (20 gal) with universal compatibility for hot rods, street cars, track cars, trucks, and SUVs. It includes an 8AN inlet/outlet and a built-in 0–90 ohm level sensor with a 12-foot fuel line kit. Choose this if you need more fuel capacity without sacrificing aluminum strength and level monitoring. A limitation to consider is the need to ensure the 8AN fittings align with existing line hardware in your build.
Parts-Diyer 14-15 Gallon Aluminum Fuel Cell Tank (Blue, 2nd listing)
This 15-gallon Parts-Diyer model repeats the core features: durable aluminum, 0-90 Ohm fuel sender, and a compact 30″ length with a 1.75″ filler neck cap. It’s favored for white-on-blue or white-on-piloted schemes, offering easy identification of fuel status. Best for boats needing consistent level reading and corrosion resistance, but the universal fit means you should verify mounting dimensions for non-standard hull layouts.
RDS MFG INC 62533 General Purpose Tank – 18 Gal
The RDS MFG 62533 is a general-purpose aluminum tank with fully welded seams, suitable for gravity feeding diesel or gasoline in a factory or marine setting. It offers rust resistance and a robust build. Best for long-term installations where seamless integrity and contamination prevention are priorities. Note that compatibility with top-fueling methods and matching mounting hardware should be checked before purchase.
RDS MFG INC General-Purpose Marine Fuel Tank – 13 Gal
This marine-specific tank from RDS MFG INC fits 13 gallons and is designed for gasoline auxiliary fueling, with potential to siphon from the top via an electric fuel pump. Best for boats needing a compact, marine-rated tank with straightforward installation. A limitation is the relatively smaller capacity compared to other options in this guide, which may require refueling more often on longer trips.
EVIL ENERGY 19 Gallon Fuel Cell
The EVIL ENERGY 19-gallon fuel cell provides a larger capacity with a built-in 3–90 ohm level sensor and a robust anti-slosh design. It supports multiple fuels, including diesel and variants of alcohol/fuels, but excludes certain blends like E85 when using specific lines. This tank suits boats needing sizeable fuel storage and reliable gauge feedback. Limitations include compatibility with certain fuel types and line configurations; verify your fuel type before purchase.
Buying Guide
Key purchase considerations help ensure the right choice for your boat:
- Capacity vs. space: Match tank size to available space and planned trip length. Larger tanks increase range but require hull clearance and mounting room.
- Fuel type compatibility: Most listed tanks are aluminum and suitable for common fuels, but verify acceptance of diesel, gasoline, or ethanol blends for your engine and fuel system.
- Level sensing: Some models include 0–90 Ohm level senders. If you rely on precise fuel gauging, choose a unit with a built-in sender or prepared for a compatible gauge.
- Vent and rollover protection: Top-feed vents (8 AN) reduce spills and airlock risk. Ensure proper venting for safety and compliance with marine standards.
- Mounting and fit: Check the tank dimensions against your bilge or deck space. Some tanks use standard shapes that simplify installation; others may require custom brackets.
- Finish and maintenance: Aluminum offers corrosion resistance and easy cleaning. A smooth finish reduces buildup and simplifies inspection for leaks.
Practical comparisons
- Best for compact builds: GSTP 15 Gallon and Parts-Diyer 15G blue/white tanks offer good balance of size and features for tight compartments.
- Best for higher range: GSTP 20 Gallon and EVIL ENERGY 19 Gallon provide more capacity without dramatically increasing footprint.
- Best for level awareness: Tanks with built-in 0–90 Ohm senders simplify monitoring and reduce guesswork during trips.
- Avoid this if space is extremely limited: Larger tanks require more mounting space and may necessitate custom brackets.
Frequently asked questions
- Can these aluminum tanks be used for diesel fuel? Yes, many are designed for multiple fuel types, but confirm with the seller and ensure compatibility with your engine’s fuel system.
- Do all tanks come with a level sender? Some models include a level sensor; others require separate installation of a sender.
- Are anti-slosh features common? Yes, several models include anti-slosh foam to maintain fuel pickup during movement.
- What maintenance is needed? Regular inspection for leaks, cleaning the interior as needed, and checking fittings for wear help ensure long life.
- How do I choose between 15 gal and 20 gal? Consider your typical voyage length, boat size, and available mounting space. 20 gal offers more range at the cost of additional space.
- Is aluminum fuel tank corrosion-resistant? Aluminum is chosen for its corrosion resistance and light weight, making it suitable for marine environments when properly installed.
