Replace the O-ring (7.47 x 3.6 mm) [1] and O-ring (7.45
x 3.61 mm) [2] with new ones when the fuel line is
removed/installed or replaced.
• Install the O-rings in their proper locations.
• Apply engine oil to the O-rings before installation.
• Avoid using vegetable oil and alcohol based
lubricants.
CHECK AFTER OPERATION
Check the parts for secure installation and the bolts,
screws, and other fasteners for secure tightening.
Connect the battery cable to the battery negative (–)
terminal.
FUEL LEAK CHECK
Turn the combination switch ON (but do not turn the
starter) after connecting the fuel lines. The fuel pump
(high pressure side) should operate for approximately 2
seconds and the fuel pressure in the high pressure side
fuel line should rise. Repeat this operation 2 or 3 times
and check for fuel leakage.
WHEN THE BOAT IS EQUIPPED WITH
RADIO EQUIPMENT/D-GPS
The ECM and its wires are designed to be unaffected
by radio waves. However, the ECM can malfunction
when it senses an extremely powerful electric wave.
Note the following to avoid malfunction of the ECM.
• Install the antenna and the body of the radio
equipment at least 50 cm (20.0 in) away from the
ECM, remote control cable, remote control box,
NMEA 2000 interface cable, and network cable.
• Antenna wire must not be too long. Do not route the
antenna wire along the main wire harness and other
cables/wires.
• Do not mount high output power radio equipment on
the boat. (The maximum output power of the radio
equipment should be 10 W.)
• Install the D-GPS antenna and the body unit at least
3 m away from the engine.
• Connect the D-GPS antenna ground wire to ground.
