Mercury Marine's Pressurized Portable Fuel Tank - Mercury 200 Pro XS Operation, Maintenance And Installation Manual

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.
SPECIAL FEATURES OF THE PORTABLE FUEL TANK
• The fuel tank has a two‑way valve which allows air to enter the tank as
the fuel is drawn to the engine, and also opens to vent to the atmosphere
if internal pressure in the tank exceeds 34.4 kPa (5.0 psi). A hissing noise
may be heard as the tank vents to the atmosphere. This is normal.
• The fuel tank includes a fuel demand valve that prevents pressurized fuel
from entering the engine and causing a fuel system overflow or possible
fuel spillage.
• When installing the fuel tank cap, turn the cap to the right until you hear a
click. This signals that the fuel cap is fully seated. A built‑in device
prevents overtightening.
• The fuel tank has a manual vent screw which should be closed for
transportation and open for operation and cap removal.
Since sealed fuel tanks are not vented, they will expand and contract as the
fuel expands and contracts during heating and cooling cycles of the outside air.
This is normal.
