Insert special tool 13 5 270 into disconnected fuel line. Screw onto special tool 13 5 270, the special tool 11 4 310. Screw IMIB 100 bar pressure sensor (1) on the special tool 11 4 310.

NOTE: As an alternative to the 100 bar IMIB pressure sensor (1), the 25 bar pressure sensor can also be used. For this, screw on special tool 11 5 364 instead of special tool 11 4 310 into special tool 13 5 270. Or directly screw the pressure manometer from the set of special tools 13 3 060 onto the special tool 13 5 270.
