User Guide

• The purpose of this tool is to diagnose fuel related issues such as misfire, high fuel consumption, no start situation and low or no pressure etc
• Comprehensive kit suitable for testing fuel delivery pressure on both mechanical and lectronic fuel injection systems
• Includes assorted range of hoses, banjo bolts, hose barb fittings and unions necessary to adapt to early and later model vehicles
• Suitable for petrol and low pressure side diesel system only
• Supplied in custom moulded plastic hard case with double tray lift out for easy access and identification of all parts

Note: Not suitable for diesel high pressure or petrol high pressure direct injection side

Instructions

Electronic Fuel Injection Types

• There are two basic types of electronic fuel injection systems. Central fuel injection (CFI) and multi-port injection (MPFI) fuel systems

• Central fuel injection systems commonly use one or more injectors mounted in the throttle body and spray fuel into the inlet manifold.
  Evenly distributes the fuel and air mixture into the cylinders, similar to a carburettor system

• Multi-port injection systems will have individual injectors per cylinder mounted on the intake manifold and will spray fuel simultaneously

BASIC FUEL SYSTEMS SET UP
NOTE: Always check manufacturer procedures and specifications

1. Use pressure gauge no. 1 and fit basic hose to the T-piece of the gauge. Use an appropriate thread sealant to secure connection on the adaptor (fig.1)
2. Attach the clear hose onto the pressure relief valve
3. Close bleed-off valve on the pressure gauge assembly (fig.2)
4. Depressurise the fuel system before disconnecting fuel lines off the vehicle
5. Locate the fuel outlet on the fuel system, you may require an adaptor supplied in the kit to connect the tester
6. Start the engine and check for leaks from the connections
7. Inspect the fuel pressure gauge, note down the results. Check manufacturer’s specifications for required pressure levels
8. Switch off engine
9. Release pressure using the pressure relief valve on the test gauge (fig.3) CAUTION: A small amount of fuel may be expelled
10. Remove test equipment
11. Reconnect fuel lines
12. Clean any remaining fuel, start the engine and check for leaks
    

BOSCH CONTINUOUS INJECTION SYSTEMS (C.I.S)
NOTE: Always check manufacturer procedures and specifications

1. Clean the fuel distributor to prevent dirt from entering the system
2. Use pressure gauge no. 1 and remove the gauge from the T-piece. Use an appropriate thread sealant to secure connection on the Bosch adaptor hose
3. Connect the Bosch hose to the fuel distributor, warm-up compensator hose or pressure dampening hose
4. Due to differences in vehicle manufacture it may be necessary to use one of the kit adaptors. Select the control pressure regulator side of the system
5. Release any air in the system by engaging the pressure relief valve located below the pressure gauge CAUTION: A small amount of fuel may be expelled
6. Start the engine and check for leaks from the connections
7. Read the pressure and compare with manufacturers specifications, switch engine off once completed
8. Release pressure in the test hose by depressing the relief valve below the gauge once again taking care with any expelled fuel
9. Remove testing equipment and re-connect lines
10. Start the engine and check for leaks
