5 Now the engine is ready for coupling with the FIP.
6 Prepare the F.I.P for coupling to the engine.
7 The pump plunger next to the drive end must be set to the commencement of delivery position for respective
direction of rotation.
8 Observe the timing marks on FI pump shaft and housing.
9 Rotate the pump camshaft and align the mark on the shaft taper with lines marked as R or L depending on the
