• Low permeation hose is USCG Type B1‑15 or Type A1‑15,

defined as not exceeding 15/gm²/24 h with CE 10 fuel at

23 °C as specified in SAE J 1527 ‑ marine fuel hose.

EPA Pressurized Portable Fuel Tank

Requirements

The Environmental Protection Agency (EPA) will require portable

fuel systems that are produced after January 1, 2011 for use with

outboard engines to remain fully sealed (pressurized) up to

34.4 kPa (5.0 psi). These tanks may contain the following:

• An air inlet that opens to allow air to enter as the fuel is

drawn out of the tank.

• An air outlet that opens (vents) to the atmosphere if

pressure exceeds 34.4 kPa (5.0 psi).

Fuel Demand Valve (FDV) Requirement

Whenever a pressurized fuel tank is used, a fuel demand valve

is required to be installed in the fuel hose between the fuel tank

and primer bulb. The fuel demand valve prevents pressurized

fuel from entering the engine and causing a fuel system overflow

or possible fuel spillage.

The fuel demand valve has a manual release. The manual

release can be used (pushed in) to open (bypass) the valve in

case of a fuel blockage in the valve.

a - Fuel demand valve ‑ installed

in the fuel hose between the

fuel tank and primer bulb

b - Manual release

c - Vent/water drain holes

Mercury Marine's Pressurized Portable Fuel Tank

Mercury Marine has created a new portable pressurized fuel tank

that meets the preceding EPA requirements. These fuel tanks

are available as an accessory or are provided with certain

portable outboard models.
