Safety Precautions

To prevent accidents that could result in

serious injury and/or damage to vehicle or test

equipment, carefully follow safety rules and test

procedures at all times when working on vehicles.

 Always wear approved eye protection.

 Never use Fuel Pressure Tester Kit on Diesel or

Flex Fuel engines!

 Never attach or remove Fuel Pressure Tester Kit

from fuel rail test port with ignition key on.

 Always place end of 6 foot bleed-off hose in an

approved container for fuel during testing and

when bleeding off fuel pressure.

 Never smoke or have open flames near vehicle.

Vapors from fuel and charging battery are highly

flammable and explosive.

 Never permit fuel to spill on hot engine parts. If a

spill or leak occurs, immediately turn ignition

key off, and clean up fuel.

 Only use Fuel Pressure Tester Kit for measuring

fuel pressure.

 Always operate vehicle in a well ventilated area.

Fuel Pressure Tester Kit

The Fuel Pressure Tester Kit was designed to help diagnose driveability

problems due to abnormally high or low fuel pressure

15825 Industrial Parkway

Cleveland Ohio 44135 USA (EUA)

Do not inhale exhaust gases or fuel vapors.

 Always keep yourself, tools and test equipment

away from all moving or hot engine parts.

 Always make sure vehicle is in PARK

(Automatic transmission) or NEUTRAL (manual

transmission) and parking brake is set. Block

drive wheels.

 Never lay tools on vehicle battery. Terminals may

short together causing harm to yourself, tools or

battery.

 Never leave vehicle unattended while running

tests.

 Always keep a fire extinguisher suitable for fuel/

electrical/chemical fires handy.

 Always use extreme caution when working

around ignition coil, distributor cap, ignition

wires, and spark plugs. These components

contain High Voltage when engine is running.

 Complete all Pre-Testing Checks before

beginning fuel pressure testing.

 Always follow vehicle manufacturers warnings,

cautions and service procedures.

Fuel Pressure Tester Description

1 Rubber Boot: Boot is used to protect gauge and maintain

appearance.

2 Dial Face: Contains measurement scales that show amount

of fuel pressure present in fuel system.

3 Pressure Relief Button: Used to relieve fuel pressure in

gauge hose before disconnecting gauge hose from fuel rail.

4 Bleed-Off Hose: A 6 foot hose that bleeds off fuel pressure

when pressure relief button is pressed. Never use a bleed-off

hose shorter than 6 foot.

Important: Always make sure end of bleed-off hose is in an

approved container for fuel at all times during testing and when

bleeding off fuel pressure!!

5 Gauge Hose: Hose that carries fuel to the gauge, so that

pressure can be measured.

6 GM/Chrysler Test Port Adapter: Adapter is used to connect

gauge hose to GM, Chrysler, and other vehicles equipped with a

schrader valve test port on fuel rail.

7 Ford Test Port Adapter: Adapter is used to connect gauge

hose to Ford vehicles equipped with a schrader valve test port on fuel rail.

8 GM TBI Test Adapter: Adapter is used to connect gauge hose to GM TBI vehicles NOT equipped

with a schrader valve test port.

9 M12 X 1.25 Banjo Bolt Adapter: Adapter is used to connect gauge hose to Asian, European and

select domestic vehicles equipped with fuel Banjo Bolt Connections.

10 Dual Manifold Test Adapter: Adapter is used to connect gauge hose to vehicles with rubber hose

connections on the fuel rail, fuel line, or fuel filter.

There are two basic types of fuel injection systems currently being used. The first type is called port or multi-port fuel injection. In this system, fuel injectors spray fuel directly into intake manifold behind intake valve. These systems typically have one fuel injector per cylinder. The second type is commonly called Throttle Body Injection (TBI) for GM and Chrysler vehicles or Central Fuel Injection (CFI) for Ford vehicles.
PAGE 3
Fuel Filter: A filter that is located in-line with the pressure line. Its function is to prevent foreign particles from reaching the fuel injectors. A clogged or restricted fuel filter can also cause low fuel pressure readings. This is the only fuel system component that requires periodic replacement. Refer to vehicle owners manual for replacement interval. Fuel Rail Test Port: A schrader valve located on the fuel rail that allows easy connection of a fuel pressure gauge to measure fuel pressure.
