The Attwood 8812LPG2 is a 12-gallon portable marine fuel tank with a gauge. Its capacity can suit boats that need more range than a smaller portable tank, but the tall 22.75 by 14.25 by 14.47-inch body must fit securely, remain accessible and connect to the correct fuel fittings. The full part number matters because Attwood sells a different low-profile 12-gallon version.

Attwood 8812LPG2 Portable Fuel Tank
Best suited to: Outboard-powered boats that need a portable 12-gallon tank and have a secure, ventilated location sized for this exact model.
Main limitation: This is the taller 8812LPG2, not the low-profile 8812LLPG2. Fuel-line parts and engine compatibility still require separate confirmation.

The Attwood 8812LPG2 is a practical option when you specifically need a gauged 12-gallon portable tank and can accommodate its height. Measure first, identify every connector in the fuel path and follow the tank, boat and outboard instructions. Choose the low-profile model only if its different footprint is the better fit.
Who it fits and who should choose another tank
Good fit
- Outboard boats designed to use an approved portable fuel tank
- Storage locations that fit the 22.75 by 14.25 by 14.47-inch body
- Owners who want a built-in tank gauge
- Fuel systems that can use the specified 1/4-inch NPT fitting interface with the correct approved components
Choose another option when
- Your boat requires a permanently installed fuel tank
- The available space needs the separate low-profile 8812LLPG2 shape
- The tank cannot be secured and kept accessible as required by the boat and tank instructions
- You have not confirmed hose, connector, engine and fuel-system compatibility
Confirm the full model number before buying
Attwood's catalog separates four 12-gallon models. The 8812LPG2 reviewed here is the taller version with a gauge. The 8812LP2 uses the same listed dimensions but omits the gauge. The 8812LLP2 and 8812LLPG2 are lower-profile tanks with a wider and longer footprint.
This naming is easy to misread on a small retailer screen. Match the part number, not only the words “12 gallon.” If a compartment is shallow, do not assume the low-profile model and this model are interchangeable. Their shapes change where the cap, line and gauge sit in relation to surrounding structure.
What the important features mean
Automatic vacuum valve and self-sealing cap
Attwood describes an automatic vacuum valve that supports fuel flow without the manual vent adjustment used on older tank designs. The catalog also identifies a tethered self-sealing cap with an audible click. Treat those as operating features, not permission to ignore the instructions or alter the cap.
Gauge included on the LPG model
The final “G” distinguishes the gauged model in Attwood's table. A gauge helps with routine checks, but trip planning should not depend on one glance. Fuel use varies with engine, load, speed and conditions. Build a reserve into the plan and investigate a gauge that behaves unexpectedly.
Low-permeation, fuel-compatible construction
Attwood lists the tank as EPA certified and CARB approved, ethanol and alcohol compatible, and designed with low-permeation construction. Those statements describe the tank. They do not confirm that an older hose, connector or engine-side component is compatible with the fuel you use.
Measure the complete installation space
The published dimensions are 22.75 inches long, 14.25 inches wide and 14.47 inches high. Do not treat those measurements as the only clearance needed. Leave the access required by the product instructions for the cap, gauge, fitting and fuel-line route. Check that the line will not kink or rub when the boat is loaded and underway.
A 12-gallon tank also changes the weight carried when filled. Use the boat manufacturer's loading and placement guidance. The tank needs a location intended for fuel equipment, away from damage and interference. If the boat's arrangement is unclear, have a qualified marine technician assess it before use.
Plan the fuel connection as a complete system
Attwood lists compatibility with 1/4-inch NPT fuel fittings. That thread specification does not identify every part required between the tank and the outboard. Connector style, approved hose, primer bulb, engine fitting, clamps or other hardware depend on the system.
Avoid assembling a fuel path from parts selected only because they appear to fit. Follow the tank and engine manuals, and use components approved for the intended fuel application. After installation, check the complete system using the manufacturer's procedure before starting the engine.
Setup, use and inspection priorities
- Verify part number 8812LPG2 on the tank and confirm the cap, gauge and fittings match the instructions.
- Measure the installation area and plan a protected fuel-line route before filling the tank.
- Use the specified approved fittings and sealant method. Do not modify the cap or automatic valve.
- Secure the tank according to the boat and tank instructions, while keeping required controls and connections accessible.
- Inspect the tank, cap, line and connections before each trip. Stop and address fuel odor, leakage, damage or abnormal pressure behavior.
- Refuel and store gasoline only as allowed by the product, vessel and local safety requirements.

Buying context and related guidance
This tank solves a specific storage and fuel-capacity problem. It does not replace checking the boat's permitted fuel arrangement or matching the fuel line to the outboard.

The queue's clean Amazon URL identifies ASIN B006MIXFY2 and the 8812LPG2 model, but the Amazon page was not technically accessible during this review. Exact model specifications were therefore checked against Attwood's official catalog. The supplied Amazon-hosted gallery was used as exact-product imagery.
