Fuel Pressure; LH-, LU-Jetronic, Motronic Specifications:

LH-, LU-Jetronic
1. Connect appropriate pressure gauge between the fuel supply connector and the distribution pipe.
2. Start engine and run at idle, if engine will not start energize fuel pump by bridging wires 20B and 76 of the tachymetric relay.
3. Disconnect the vacuum line from the fuel pressure regulator and read line pressure w/o vacuum.
4. Apply 14.8 in Hg of vacuum to pressure regulator and read line pressure w/vacuum.
