Priming the Fuel System

Prime the fuel system before starting the engine for
the first time, after running out of fuel, or after fuel
system maintenance (e.g., draining the filter/water
separator, replacing a fuel hose).
To prime the fuel system, perform the following steps:
1. Ensure that fuel is in the fuel tank.
2. Turn the ignition key to the O
to 15 seconds.
Note:
This allows the fuel pump to prime the
fuel system.
Important:
Do not use the engine starter motor to
crank the engine to prime the fuel system.
