3 Fix the FI pump on its engine bracket - move it to the engine side - insert the drive side half coupling on the
drive shaft of the air compressor or exhauster (depending on the make of the engine).
4 Insert the fastening bolts on the pump mounting holes and tighten them with nuts to the specified torque.
5 Crank the engine and check for free rotation of the pump shaft along with exhauster/air compressor shaft.

1 Disconnect the first injector pipe at the FIP’s end.
2 Remove the 1st delivery valve holder and remove the valve pin and spring and fit the delivery valve holder
3 Fit the swan neck pipe (1) on the 1st delivery valve holder. (Fig 1)
4 Connect the fuel gallery of the FIP to the fuel container placed at a higher level.
5 Move the FIP towards the engine till the fuel (2) starts flowing freely through the swan neck pipe.
6 Now move the FIP away from the engine till the fuel flow is cut off completely.
7 Again move the FIP towards the engine and stop when the fuel flow regulates in such away that there is a flow
of a drop (3) between 15 and 20 seconds; at that time tighten the bolts of the FIP flange without varying the
flow of the drop.
8 Remove the swan-neck pipe (1) and delivery valve holder and replace the pin and spring and fit the delivery
