Right installation For N54 High Pressure Fuel Pump

1.Firstly, you need to check the connection between body pump and pressure valves, see if it is tackless or not. If this unusual situation happens, please get in

contact with us ASAP and DO NOT install the pump. Your cooperation will help each other avoid unnecessary loss.(The main cause of tackless part is the improper

operation of the express company, most situation is squeezing and crashing during transit ).

2. Before installation, you need to wash the oil circuit and change the pump strainer first. High quality gas is highly requested when high pressure fuel pump works, impure

gas will create terrible damage to HPFP. If you didn’t wash the oil circuit, the HPFP may reduce use age after installation.

3. Please check the O Ring before installation, make sure the O ring is flat on the pump. It is highly requested when install the HPFP.
