FUEL PUMP PRIME PROCEDURE
CAUTION
Performing this procedure can present a potential fire
hazard. Verify all fuel hoses are secured and there are
no fuel leaks. Do not smoke or perform procedure
around open flame.
IMPORTANT
Verify there is a sufficient amount of fuel in the fuel tank
to prevent fuel pump damage.
The fuel pump prime procedure will purge air out of the
fuel system in the event the fuel tank was run dry and the
engine is difficult to re-start after re-filling the fuel tank.
