High Pressure Pump With Fuel Pressure Regulator Valve, Assembly Overview

High Pressure Pump with Fuel Pressure Regulator Valve, Assembly Overview

CAUTION!
Fuel system is under high pressure! Before opening the system, perform the procedure for releasing fuel pressure. Procedure, see => [ Releasing Pressure in High Pressure Area ] Releasing Pressure In High Pressure Area.





1 - Roller tappet

• remains inserted in cylinder head after removing the high-pressure pump, removable

2 - O-ring

• Replace

3 - Mechanical single-piston high-pressure pump

• An electrical fuel pump, located in the fuel tank, supplies fuel to the mechanical high-pressure pump at a pressure of approximately 7 bar

• Make sure dirt does not enter the fuel system when installing the high pressure pump.

• The fuel system must be pressureless, releasing fuel pressure => [ Releasing Pressure in High Pressure Area ] Releasing Pressure In High Pressure Area

• Do not install fuel lines with tension
