11) On AWD model, after removing fuel sub meter unit,
drain fuel from there.
WARNING:
Do not use a motor pump when draining fuel.
2. On-Car Services
A: MEASUREMENT OF FUEL PRESSURE
1) Release fuel pressure.
2) Connect connector to fuel pump.
G2M0347
3) Disconnect fuel delivery hoses from fuel filter, and con-
nect fuel pressure gauge.
G2M0348
4) Start the engine.
5) Measure fuel pressure while disconnecting pressure
regulator vacuum hose from collector chamber.
Fuel pressure:
235 — 265 kPa (2.4 — 2.7 kg/cm
2, 34 — 38 psi)
6) After connecting pressure regulator vacuum hose, mea-
sure fuel pressure.
Fuel pressure:
177 — 206 kPa (1.8 — 2.1 kg/cm
2, 26 — 30 psi)
WARNING:
Before removing fuel pressure gauge, release fuel
pressure.
NOTE:
If out of specification as measured at step 6), check or
replace pressure regulator and pressure regulator vacuum
hose.

A: REMOVAL
1) Release fuel pressure.
G2M0347
2) Disconnect fuel delivery hoses from fuel filter.
3) Remove filter from holder.
B: INSPECTION
1) Check the inside of fuel filter for dirt and water sedi-
ment.
2) If it is clogged, or if replacement interval has been
reached, replace it.
3) If water is found in it, shake and expel the water from
inlet port.
