If reduction of fuel supply is suspected, perform checking as follows.

PREPARATION
- Make sure that there is fuel in the tank.
- With the engine running, check the fuel feed pipe and hose from fuel tank to injector for evidence of leakage.
Retighten, if pipe or hose connection is loose.
Also, check pipes and hoses for squashing or clogging.

INSPECTION

- Disconnect the fuel line at the filter outlet.
- Receive the hose from fuel feed pipe with a clean container, and check for fuel pump flow rate.

CAUTION: Never generate sparks when connecting a jumper wire.

Fuel Pump Relay Connector:

- Connect the pump relay terminals with a jumper wire as shown and start the fuel pump to measure delivery.

VOLUME SPECIFICATION
