EPA requirements for outboard fuel line connectors
Since January 2011, the EPA has required that all portable fuel systems used with outboard motors follow a zero-emissions policy. Portable fuel tanks must be fully sealed and plumbed to sprayless marine fuel line connectors that eliminate the hazard of fuel spraying when connecting or disconnecting fuel lines. Each unique assembly includes a low-permeation fuel line (that meets EPA requirements), a primer bulb, a fuel demand valve (FDV), and a hose connector to fit specific makes and models of outboard motors.
The EPA's requirements for outboard fuel line connectors are part of its broader Fuel System Standard, which it shares with the US Coast Guard. The Fuel System Standard applies to gasoline fuel systems on recreational boats, both inboard and outboard. The standard requires that fuel tanks be vented with a flame arrestor or be designed to prevent a flame front from igniting fumes in the vent. Charcoal filters may be required on vent lines. Canisters must not get water or liquid fuel in them, so there must be a means to prevent water intrusion in the vent line.
The EPA's Fuel System Standard also requires that the fuel pump on a boat be on or within twelve inches of the engine. This way, the only line under pressure is the one from the fuel pump to the carburetor or fuel injection system. This line is usually very short, generally about a foot or maybe two on larger engines. The fuel from the tank is sucked to the engine rather than pushed. Pressurized lines and fuel systems are not allowed on boats, except for this one short line. The new EPA Fuel system rules do allow for up to 1 psi in the tank, fill, and vent.
Fuel hose must meet stricter standards for evaporative emissions. When used, the hose must be either USCG Type A1-15 or USCG Type B1-15. From the fuel inlet on the engine (usually the fuel pump) to the carburetor, Type A1-15 must be used. Each fuel vent line or fill line must be USCG Type A1-15, and the line from the fuel tank to the engine inlet must be Type A1-15; then you may use Type B1-15.
