7.1 Connecting the pressure pickup module
(example showing connection to Common Rail high pressure pump CP1)
- Ignition SWITCHED OFF!
- Clean the high pressure pump thoroughly with cold cleaner and blow dry with compressed air.
- Detach the system high pressure line from the pump and the rail.
Depending on the fit situation, make sure no fuel leaks onto the radiator hoses or belt, as they
are not fuel-resistant!
- Close off the rail port with a plastic plug.
- Connect the 60 MPa hose to the high pressure pump using the appropriate adapter (3), angle,
nut and thrust ring (left-hand thread).
- Connect the hose to the pressure pickup module (2).

using a second wrench!

module.
