Precautions When Working With Fuel injectors

OBSERVE THE FOLLOWING PRECAUTIONS WHEN REMOVING AND INSTALLING THE INJECTORS.



- Never reuse the 0-ring.
- When placing a new 0-ring on the injector, take care not to damage it in any way.
- Coat a new 0-ring with spindle oil or gasoline before installing-never use engine, gear or brake oil.



- Install the injector to the delivery pipe and intake manifold as shown in the illustration.

NOTE: CHECK THAT THERE ARE NO FUEL LEAKS AFTER PERFORMING MAINTENANCE ANYWHERE ON THE FUEL SYSTEM.



1. Using a jumper wire or special service tool (SST), connect terminals +B and FP of the data link connector 1 (DLC1). (SST# 09843-18020)



2 With engine stopped, turn the ignition switch ON.



3 Pinch the fuel return hose.
- The pressure in the high pressure line will rise to approx. 392 kPa (57 psi).

NOTICE: Always pinch the hose. Avoid bending as it may cause the hose to crack.
