TO MEASURE FUEL PRESSURE BEFORE THE FUEL FILTER

NOTE:
Ensure that the ignition is OFF before commencing.

Assemble the items as shown in and connect to fuel inlet side of filter.
Switch on ignition for lift pump to pressurise the system.
Start the engine and check the arrangement for leaks. If any leaks are evident, switch off engine immediately. Dry any spillages and re-assemble ensuring no leakages.
Run the engine until the pressure gauge is reading a steady pressure. Check the pipes for flowing, clean and bubble free fuel.
Rev the engine to ensure that pressure is maintained through the rev range.
Switch off the engine and DO NOT disconnect the arrangement until the fuel pressure has dropped.

TO MEASURE FUEL PRESSURE AFTER THE FUEL FILTER

NOTE:
Ensure that the ignition is OFF before commencing.

Assemble the items as shown in and connect to fuel outlet side of filter
Switch on ignition for lift pump to pressurise the system.
Start the engine and check the arrangement for leaks. If any leaks are evident, switch off engine immediately. Dry any spillages and re-assemble ensuring no leakages.
Run the engine until the pressure gauge is reading a steady pressure. Check the pipes for flowing, clean and bubble free fuel.
Rev the engine to ensure that pressure is maintained through the rev range.
Switch off the engine and DO NOT disconnect the arrangement until the fuel pressure has dropped.
When testing for positive/negative pressure, set up equipment as per and replace the gauge (item 2) with gauge (item 1).
Always keep the components clean and free of oil and grease. Clean them regularly with a non-aggressive cleaner, ensuring they are dry before storage.

WARNING
DO NOT disconnect the unit from the fuel line until the pressure gauge reads zero
