e.
Suction Piping Installation. Ensure the suction piping is installed properly. Notify unit maintenance
if suction piping is not installed properly or is leaking.
f.
Preparation for Starting.
(1)
With the clutch disengaged, turn pump shaft manually using the coupling to the gearbox.
Ensure all rotating components are free to rotate.
WARNING
Both supply and return 3-way fuel valves must be aligned to the same selected fuel supply
(auxiliary or unit tank). Alignment to different supplies could cause engine overheating,
shutdown from rapid fuel exhaustion, or fuel system over-flow and the associated fire hazards.
CAUTION
If it is necessary to fill the fuel tank, clean any moisture or dirt from around fuel tank filler cap.
(2)
Align the two 3-way fuel valves (1) to the
selected fuel supply.
CAUTION
Never operate the pumping assembly unless the pump casing
is filled to the top of the suction port. The pump will not prime
when dry. Extended operation of a dry pump will destroy the
seal assembly and cause overheating which could seriously
damage the pump.
NOTE
Ensure pump body is filled to top of suction port so pump will prime properly during
startup.
