Fuel Delivery System
WARNING
Boating standards (NMMA, ABYC, etc.), federal standards and U. S. Coast Guard
regulations for INBOARD engines must be adhered to when installing fuel delivery
system. Failure to comply could result in severe personal injury or death.
CAUTION
Remove plastic plug from fuel inlet fitting. Attach fuel line to fuel fitting with U.S.
Coast Guard approved hose clamp. Inspect for fuel leaks.
1. Fuel pickup should be at least 25 mm (1 in.) from the bottom of the fuel tank to prevent
picking up impurities.
2. Fuel lines used must be U.S. Coast Guard approved (USCG type A1), fittings and lines
must not be smaller than 8mm (5/16 in.) I.D.
3. On installations requiring long lines or numerous fittings, larger size lines should be
used.
4. Fuel line should be installed free of stress and firmly secured to prevent vibration and/or
chafing.
5. Sharp bends in fuel line should be avoided.
6. A flexible fuel line must be used to connect fuel line to engine fuel pump to absorb deflec-
tion when engine is running.
7. A primer bulb is not necessary with this application. If a primer bulb is used, it must be
U.S. Coast Guard approved for inboard engine installations.
