FUEL INJECTION CONTROL SYSTEM INSPECTION
EF & EC-130prose procedureFuel Pressure Check (Cont'd)
- 9Start engine and read indication of fuel pressure gauge as vacuum is changed.
SEF718B
IMPORTANT
Fuel pressure should decrease as vacuum increases. If results are unsatisfactory, replace fuel pressure regulator.
Injector Removal and Installation
- 1Release fuel pressure to zero.
- 2Remove I.A.A. unit and intake manifold stay.
- 3Disconnect pressure regulator vacuum hose.
- 4Remove fuel tube assembly fixing bolts.Be careful not to damage the injector, nor to deform the fuel tube.

CAUTION
CAUTION:
CAUTION
Do not reuse old O-rings.
CAUTION
Apply a coat of engine oil (SAE 10W-30) to new O-rings. Do not use solvent for wiping.
CAUTION
Keep O-rings and their mating parts clean and free from foreign particles (dirt, ravelings, etc.) before installation.
CAUTION
Do not scratch the O-ring either with tools or finger nails during installation. Be careful not to expand or twist excessively. Do not insert into fuel tube immediately after expansion.
