Low Permeation Fuel Hose Requirement; Filling Fuel Tank - Mercury 25 EFI FourStroke User Manual

Low Permeation Fuel Hose Requirement

Required for outboards manufactured for sale, sold, or offered
for sale in the United States.
• The Environmental Protection Agency (EPA) requires that
any outboard manufactured after January 1, 2009 must use
low permeation fuel hose for the primary fuel hose
connecting the fuel tank to the outboard.
• 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.

Filling Fuel Tank

Avoid serious injury or death from a gasoline fire or explosion.
Use caution when filling fuel tanks. Always stop the engine and
do not smoke or allow open flames or sparks in the area while
filling fuel tanks.
Fill fuel tanks outdoors away from heat, sparks, and open
flames.
Remove portable fuel tanks from boat to refill them.
Always stop engine before refilling tanks.
Do not completely fill the fuel tanks. Leave approximately 10% of
the tank volume unfilled. Fuel will expand in volume as its
temperature rises and can leak under pressure if the tank is
completely filled.
PORTABLE FUEL TANK PLACEMENT IN THE BOAT
Place the fuel tank in the boat so the vent is higher than the fuel
level under normal boat operating conditions.
