Fuel Pressure Gauge Kit - PU-43506-A

IMPORTANT: The EFI fuel system remains under high

pressure, even when the engine is not running. Before

attempting to ser vice any part of the fuel system,

pressure mus t be reliev ed ( if ap plicable). The F uel

Pressure Gauge Kit has an integrated pressure relief

valve that can be used to bleed off pressure once you

have completed the fuel pressure test.

Diagnostic Software - PU-47063-A

This de aler-only sof tware inst alls on laptop co mputers

equipped with a CD drive and serial port connection, and

is designed to re place multiple shop tools often used to

test EF I comp onents. It also includ es step-by-step

diagnostic pr ocedures to a id techn ician r epair an d

troubleshooting.

IMPORTANT: If the PC you are using is not equipped

with a 9-pin serial port, a USB to serial port adaptor

will be necessary. A USB to serial port adaptor can be

purchased through DSA at: www.diagsys.com

WARNING

Gasoline is extremely flammable and explosive

under certain conditions.

* EFI components are under high pressure.

Verify system pressure has been

relieved before disassembly.

* Never drain the fuel system when the engine is hot.

Severe burns may result.

* Do not overfill the tank. The tank is at full capacity

when the fuel reaches the bottom of the filler neck.

Leave room for expansion of fuel.

* Never start the engine or let it run in an enclosed area.

Gasoline powered engine exhaust fumes are

poisonous and can cause loss of consciousness

and death in a short time.

* Do not smoke or allow open flames or sparks in or near

the area where refueling is performed or where

gasoline is stored.

* If you get gasoline in your eyes or if you should

swallow gasoline, seek medical attention immediately.

* If you spill gasoline on your skin or clothing,

immediately wash with soap and water

and change clothing.

* Always stop the engine and refuel outdoors

or in a well ventilated area.
