Matching a portable outboard fuel system begins with three choices: three or six gallons of tank capacity, whether you want a fuel-level gauge, and the hose diameter and connector arrangement your engine needs. Attwood's low-permeation tanks and universal primer-bulb hoses come in distinct manufacturer part numbers—check them before ordering.

Attwood fuel tank and hose comparison
| Part number | Type / option | Capacity or length | Dimensions or hose ID | Fuel connection |
|---|---|---|---|---|
| 8803LP2 | 3-gallon tank, no gauge | 3 US gal | 16.6 × 11.45 × 7.3 in | ¼-in NPT tank port |
| 8803LPG2 | 3-gallon tank with gauge | 3 US gal | 16.6 × 11.45 × 7.3 in | ¼-in NPT tank port |
| 8806LP2 | 6-gallon tank, no gauge | 6 US gal | 19.82 × 13.50 × 9.16 in | ¼-in NPT tank port |
| 8806LPG2 | 6-gallon tank with gauge | 6 US gal | 19.82 × 13.50 × 9.16 in | ¼-in NPT tank port |
| 951606ULP7 | 5/16-in primer-bulb line | 6 ft long | 5/16-in hose ID | No tank or engine fittings included |
| 93806ULP7 | 3/8-in primer-bulb line | 6 ft long | 3/8-in hose ID | No tank or engine fittings included |
| 93806UFDV7 | 3/8-in line with demand valve | 6 ft long | 3/8-in hose ID | No tank or engine fittings included |
Tank dimensions are manufacturer exterior dimensions in inches. Hose ID is inside diameter and is not the same measurement as the tank's threaded fitting.
Five checks before selecting marine fuel parts
- Measure the available space and select the three-gallon or six-gallon tank footprint, allowing for access and secure storage.
- Use the exact tank MPN to choose a gauge-equipped or non-gauge model. Both tank sizes use ¼-inch NPT fuel fitting ports.
- Match the engine's required 5/16-inch or 3/8-inch hose inner diameter; do not choose based only on hose length.
- If the system requires a fuel-demand valve, compare 93806UFDV7 rather than assuming the basic low-permeation line has one.
- Identify compatible tank-side and outboard-side connectors separately. Inspect the line, primer bulb, clamps and fittings for condition, and follow fuel-system and ventilation requirements.

Three- and six-gallon portable tanks
The four LP2-series tanks differ by capacity and whether a fuel-level gauge is included. Their threaded tank ports do not determine the correct outboard-side connector.
Universal primer-bulb fuel lines
All three illustrated hose assemblies are six feet long and require separately selected tank and engine fittings. Choose the correct hose inside diameter and fuel-demand-valve arrangement.
