FuelFilter
Replacement
r@. Do not smoke whilc working on fuel system. Keep
open flame away from your work arsa.
. While replacing the tuel filter, be catelul to koep a
sale distance betwoen battery torminals and any
tools.
The fuel filter should be replaced whenever the fuel
pressure drops below the specified value [260 - 310 kPa
12.7 - 3.2 ksl/cm',38 - 46 psi), |270 - 320 kPa (2.8 - 3 3
kgf/cm,, 40 - 47 psi))* with the fuel pressure regulator
vacuum hose disconnected and pinchedl after making
sure that the fuel pump and the fuel pressure regulator
are OK. *: 81642 engine
1. Place a shop towel under and around the fuelfilter.
2. Relieve fuel pressure (see pages 11-230,231]-
Remove the 12 mm banjo bolt and the fuel feed
pipe from the fuel filter, while supporting it with the
another wrench, as shown.
Remove the fuel filter ciamp and fuel filter'
lnstall the new fuel filter in the reverse order
removal, and note these items:
a When assembling, use new washers as shown
. Clean the flared joint of high pressure hoses
thoroughly before reconnecting them.

Evaporative Emission (EVAPI Controls
Description
The evaporative emission controls are designed to minimize the amount of fuel vapor escaping to the atmosphere. The
system consists of the foliowing components:
A. Evaporative Emission (EVAP) Control Canisto]
An EVAP control canister is used for the temporary storage of fuel vapor until the fuel vapor can be purged from the
EVAP control canister into the engine and burned.
B. Vapor Purge Control System
EVAP control canister purging is accomplished by drawing fresh air through the EVAP control canister and into a port
on the intake manifold. The purging vacuum is controlled by the EVAP purge control solenoid valve.

Fuel Tank Vapor Control System
When fuel vapor pressure in the fuel tank is higher than the set value of the EVAP two way valve, the valve opens and
regulates the flow of fuel vapor to the EVAP control canister.
Onboard Refueling Vapor Recovery (ORVRI System {'99 - 00 models}
During refueling. the oRVR {onboard Refueling Vapor Recovery) vent shut valve opens with the pressure in the fuel
tank. and feeds the fuel vapor to the EVAP control canister.

The line pressure (5) changes to the 2nd ctutch pfessure l2O) at the 2-3 shift valve. The 2nd clutch pressure(20) is applied to the 2nd clutch, and the 2nd clutch is engaged.
Fluid flows by way of:- Line Pressure (4) + cPB varve - Line pressure (s) * 'r-2 shift varve - Line pressure (5) * 2-3 shift varve- 2nd Clutch Pressure (20) + 2nd Clutch
The hydraulic pressure also flows to the 1st clutch. However, no power is transmittod because of the one-way ctutch.
