Installing the Fuel Pump
Make sure the engine has cylinder number 1 at TDC.
The keyway in the shaft of new and reconditioned

the keyway in the drive gear when cylinder number 1
is at TDC on the compression stroke.
After verifying that Cylinder Number 1 if at TDC,
install the pump. Make sure the key does not fall into
the gear housing.
Attach the pump by finger tightening the three
mounting nuts. The pump must be free to
move in the slots.
