PROCEDURE FOR PRIMING THE FULE CIRCUIT OF BOSCH ROTARY FIP WHEN THE FUEL CIRCUIT GETS EMPTY Caution – Please note that the Rotary FIP is lubricated by Diesel, in case of FIP is run dry due to diesel starvation, it could lead to severe damage of FIP internal parts. Always monitor the fuel level in the tank •Ensure the fuel circuit connections are complete without any leaks or breakage in the hoses and ensure that the suction tube is below fuel level (Completely immersed in fuel in fuel tank) Priming the Fuel Filter •Loosen the air vent screw on the main filter • Start priming by repeatedly pressing the hand primer (Hand primer shown in figure is on filter assembly as in majority application codes, whereas the hand primer location could be different in some cases, please locate the hand primer by checking the fuel line) •Continue the same till the fuel starts spilling from the air vent screw (This indicates that the air in the circuit is fully vented) •Screw in the air vent screw and tighten it by hand
•Continue to press the hand primer repeatedly for 5-10 more strokes, tighten the air vent screw to specified (0.9 Kg m) torque 96
