Attwood Marine Low Profile Portable Fuel Tank, 12 gal, 1/4 in NPT, EPA/CARB, 24 x 18 x 11.61 in

Overview

The Attwood Marine Portable Low Profile Fuel Tank is a 12-gallon portable marine fuel tank made for boats that need more fuel capacity without a tall tank taking up deck or storage space. Its low-profile shape measures 24 inches long, 18 inches wide, and 11.61 inches high, giving it a stable footprint for pontoon boats and other small craft where tank height matters.

The tank uses UV-grade, multi-layer construction and is built for the pressure changes found in closed portable fuel systems. It works with 1/4-inch NPT fuel fittings and uses an EPA cap with a high-flow automatic vacuum valve, so there is no manual thumb-screw vent to open before running the engine.

This range is available with or without a fuel gauge. Both versions share the same 12-gallon capacity and low-profile layout, with the gauge version giving a faster fuel-level check during long days on the water.

Key features

• 12-gallon capacity gives more run time between fuel stops for pontoon boats, fishing trips, and extended cruising close to shore.
• Low-profile body is 3 inches lower than regular 12-gallon tanks, helping it fit under seats, in open deck spaces, and in other height-limited areas.
• 24 inch by 18 inch footprint with an 11.61 inch height helps the tank sit securely while keeping the fill cap and fittings accessible.
• Compatible with 1/4-inch NPT fuel fittings for connection to matching portable marine fuel hose assemblies.
• EPA cap includes a high-flow automatic vacuum valve for proper fuel flow without manual venting.
• UV-grade, multi-layer tank material helps handle sun exposure and regular use in a marine environment.
• Meets EPA and CARB regulations and complies with ABYC/NMMA requirements for portable marine fuel tanks.
• Fuel line is not included, so the hose assembly should be matched separately to the engine and fitting setup.

Variants

This portable fuel tank is offered in two configurations based on whether a fuel gauge is included.

The capacity, low-profile shape, fitting size, cap style, and overall dimensions remain the same across the two versions. The difference is the fuel-level display on the tank.

• 8812LLPG2: With gauge, Yes. The built-in gauge gives a quick visual fuel-level check before leaving the dock and during longer outings.
• 8812LLP2: With gauge, No. This version keeps the tank simpler when fuel level is tracked during refueling or checked by routine use habits.

Installation and fit

Before installing or storing the tank on board, confirm the available space against the 24 inch length, 18 inch width, and 11.61 inch height. The low height is useful under pontoon seating, in open cockpit storage areas, and anywhere a taller portable tank would interfere with covers, cushions, or access panels.

Use a compatible marine fuel hose assembly with 1/4-inch NPT fittings and route the line so it is not kinked, pinched, or rubbing against sharp edges. The tank should remain accessible for filling, cap removal, and routine inspection.

Fuel system notes

The automatic vacuum valve in the cap helps maintain fuel flow in a closed portable tank system without the user opening a manual vent. This is helpful on boats where the tank may sit in the sun, see temperature swings, or be moved between storage and operating positions.

The multi-layer construction is meant to handle the pressure build-up associated with modern closed fuel systems. As with any portable fuel tank, keep it secured, keep it away from heat sources, and inspect the cap, fittings, and hose connections before use.

Use on board

This tank is a practical match for pontoon boats, small fishing boats, tenders, and other outboard-powered boats that use a portable fuel setup. The 12-gallon capacity is useful when a smaller tank would require frequent refilling, while the low-profile shape helps keep the tank from becoming a tall obstruction on deck.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
