3.1

relIeVING fuel sYsteM pressure.

NOTE! The following instructions are intended as a guide only.

Always adhere to manufacturer's procedures for relieving

system pressure.

3.1.1 Before disconnecting the fuel lines to connect adaptors

and pressure gauge to fuel system, the fuel system

pressure must be relieved, this will prevent fuel

spraying when a joint is disconnected.

3.1.2 Switch off ignition, loosen the fuel tank cap to relieve

tank pressure, then re-tighten.

3.1.3 To relieve fuel pressure, it is necessary to prevent the

fuel pump operating, whilst still allowing both injection

and ignition systems to operate.

3.1.4 The procedure may simply require the fuel pump relay,

fuse or electrical supply to be disconnected; some

models have two fuel pumps - make sure both are

disabled.

3.1.5 Once pump(s) is/are disabled, run the engine until it

stalls, and then crank over 5 to 10 times after it has

stalled.

On some electronic fuel injection systems, removing the

fuel pump fuse disables both the fuel pump and the

injectors. In this case refer to manufacturer's procedure.

WArNING! Do Not assume that pressure in the fuel

system has been relieved. When disconnecting, wrap a

cloth around the fuel line fitting to absorb any fuel

leakage.

3.2

CoNNeCtIoN AND usAGe.

3.2.1 With the engine off and the fuel system pressure

relieved, install the correct adaptor into the fuel system

at the point to be tested and connect to the quick

coupler on the gauge hose ensuring the locking collar is

in position.

NOTE! Use a cloth around the fittings to absorb any fuel.

3.2.2 Re-connect the fuel pump(s).

3.2.3 Start engine and allow to idle.

3.2.4 Read the fuel pressure on the gauge and compare to

the manufacturer’s specification.

3.2.5 Turn off the engine.

3.2.6 Place the end of the clear tube in a suitable container

and push the relief button to depressurise the system.

3.2.7 Remove the tester and adaptors from the fuel line.

3.2.8 Restore fuel line to original condition, restart the engine

and check the system for leaks.
