Fuel Pressure Regulators - Test Procedure & Specifications

AIR COOLED AFC

- connect gauge US 1076 to fuel ring main

- disconnect hose between intake air distributor and pressure regulator

- start engine and run at idle

 pressure should be: 2.5 bar (36 psi)

- re-connect hose

 pressure (at idle) must drop to approx. 2.0 bar (29 psi)

If pressure too low, check fuel pump delivery rate

If pressure too high, check return line

If readings still incorrect, replace pressure regulator



WATER COOLED - DIGIJET

- run engine at idle speed and check pressure

Specifications:

bar (psi) vacuum hose 2 (shown in above illustration)
approx. 2.0 (29)
approx. 2.5 (36) connected
disconnected

Copied from my Bentley CDROM pp. 24-5 (AFC) and 24-25 (Digijet)

Good luck
