Inspect fuel pressure sensor sealing surface on fuel rail (1).
Lubricate sensor threads with clean diesel fuel.
CAUTION:
Only use a socket when installing the fuel pressure sensor. Failure to follow these instructions will damage the fuel pressure sensor.

NOTE:
Do not use an impact socket, the socket wall is too thick and will not work.
Using a 27 mm thin walled socket (3), install fuel pressure sensor (2). Tighten sensor to 70 N.m (52 ft. lbs.).
