WARNING: This page is about a different car, the 2013 BMW 550i GT, 2012 BMW 550i GT, 2011 BMW 550i GT, and 2010 BMW 550i GT. However, it is still accessible from the selected car via links, so may be relevant.

To check the fuel holding pressure, special tool 13 0 290 must be assembled as follows.

Screw adapter 11 4 310 onto line 13 0 291 . Screw the IMIB 100 bar pressure sensor (1) onto adapter 11 4 310.

Alternatively, the pressure gauge from the set of special tools 13 3 060 can be screwed onto line 13 0 291 .

Between lines 13 0 291 and 13 0 292 , mount a shutoff tap (2) and a T-piece (3) from the set of special tools 13 3 060 .

Mount pressure gauge (4) from special tool set 13 3 060 onto T-piece (3) from special tool set 13 3 060 .
