Measuring, all engines
Connect manometer 9996065 with the manometer
quick-release connectors to tool 9996666.
Open the fuel cock.
Run the engine at an increased engine speed. Reduce
the engine speed (rpm) to low idling speed. Read off
the pressure within one minute.
The feed pressure should be:
Feed pump 3581310* 45–55 kPa (6.5–8.0 psi).
The feed pressure after the fuel filter should never
drop below 0 kPa for any of the pumps.
Low feed pressure can be caused by a blocked filter,
restricted fuel line, etc. Check for reduced flow (a
trapped line for example).
