Fuel Pressure: Testing and Inspection
Connecting and Bleeding Pressure Gauge
General
The tester should be connected into the control pressure line at the mixture control unit.
The control pressure now is transmitted from the mixture control unit, through the three-way selector valve, to the control pressure regulators for warm
running compensation or throttle valve position respectively.
Thus, all pressure tests can be performed without reconnecting the lines.
For better clarity, connecting points and lever positions are referenced in the instructions given below according to numbers shown in the adjacent
illustration.
Connecting and Bleeding Pressure Tester
1. Detach pressure lines for control pressure regulators for warm running compensation and throttle valve position.
2. Insert a gasket in the special tool connector and screw into the control pressure connection of the mixture control unit in place of the banjo bolt.
