Fuel Supply System
System Description
The fuel supply system consists of a fuel tank, in-tank
high-pressure fuel pump. PGM-Fl main relay, fuel filter,
fuel pressure regulator, fuel injectors, and fuel delivery
and return lines. This system delivers pressure-regulat-
ed fuel to the fuel injectors and cuts the fuel delivery
when the engine is not running.
Fuel Pressure
Relieving
Before disconnecting fuel pipes or hoses, release pres-
sure from the system by loosening the 12 mm banjo
bolt on the too of the fuel filter.
Do not smoke while working on the fuel system.
Ke€p open flames or sparks away from your work
area,
Be sure to relieve fuel pressure while the ignition
switch is off.
Write down the frequencies for the radio's preset
buttons.
Disconnect the battery negative cable from the bat-
tery negative terminal.
Remove the fuel fill cap.
Use a box end wrench on the 12 mm banjo bolt at
the fuel filter while holding the fuel filter with anoth-
er wrench.
Place a rag or shop towel over the '12 mm banjo bolt.
Slowly loosen the 12 mm banjo bolt one complete

1, Relieve fuel pressure.
2. Remove the 12 mm banjo bolt on the fuel filter while
holding the fuel filter with another wrench. Attach
the 12 mm fuel pressure adapter bolt and the special
tool.
FUEL PRESSUREREGULATON

The illustration shows'97 - 98 models,'99 - 00 models are similar.
Start the engine. Measure the fuel pressure with the
engine idling and the vacuum hose of the fuel pres-
sure regulator disconnected from the fuel pressure
regulator and pinched. lf the engine will not start,
turn the ignition switch on (ll), wait for two seconds,
turn it off, then back on again and read the fuel
pressure.
Pressure should be:'97 - 98 mod€ls:
260 -31O kPa 12.7 - 3.2 kgf/cm,, 38 - 46 psil'99 - 0O models:
270 - 32O kPa Q.A - 3.2 kgf/cm', ifo - /U psil
Reconnect vacuum hose to the fuel pressure regulator.
Prgs3ure should be:'97 - 98 models:
210 - 25O kPa 12.1- 2.6 kgf/cm', 30 - 37 psi)'99 - 00 models:
22O -26iJ kPa 12.2 - 2.7 kgt/cm', 31 - 38 psi)
lf the fuel pressure is not as specified, first check the
fuel pump (see page 11- 183). lf the fuel pump is OK,
check the following:
. lf the fuel pressure is higher than specified,
inspect for:- Pinched or clogged fuel return hose or line.- Faulty fuel pressure regulator (see page 11-
181).
. lf the fuel pressure is lower than specified. inspect
for:- Clogged fuel filter.- Faulty fuel pressure regulator (see page 11-
1811.- Fuel line leakage.

13. lnstall and tighten the retainer nuts.
14. Connect the vacuum hoses and fuel return hose to the fuel pressure regulator.
15. Connect the PCV valve.
16. Connect the connectors to the fuel injectors, the IAT sensor ('97 - 98 models), and the EVAP purge control solenoid
valve {'97 - 98 models).
Coat a new O-ring with clean engine oil, and install the resonator chamber ('99 - 00 models).
Turn the ignition switch ON (ll), but do not operate the starter. After the fuel pump runs for approximately two seconds,
the fuef pressure in the fuel line rises. Repeat this two or three times, then check whether there is any fuel leakage.

Positive Grankcase Ventilation (PGVI System
Description
The Positive Crankcase Ventilation (PCV) svstem is
designed to prevent blow-by gas from escaping to the
atmosphere. The PCV valve contains a spring-loaded
plunger, When the engine starts, the plunger in the PCV
valve is lifted in proportion to intake manitold vacuum and
the blow-by gas is drawn directly into the intake manifold.

Front Brake Pads
Inspection and Replacement
1.
Nsvgr u9e an air hose or dry brush to clean brake
assemblies.
Use an OSHA approved vacuum cleaner to avoid
broathing brake dust.
Loosen the front wheel nuts slightly, then raise the
vehicle, and make sure it is securely supported.
Remove the front wheels.
Remove the caliper bolt, and pivot the caliper up
out of the way. Check the hoses and pin boots for
damage and deterioration.

4. Using vernier calipers, measure the thickness of
each brake pad lining. The measurement does not
include the pad backing plate thickness.
Brake Pad Thickness:
Standard: 10.5 - 11.5 mm {0.,11 - 0.45 in)
Servics Limit: 1.6 mm (0.06 in)
lf the brake pad thickness is less than the service
limit. replace the front pads and shims together as a
set.
Clean the caliper thoroughly; remove any rust, and
check for grooves and cracks.
Check the brake disc for damage and cracks.
Install the pad retainers.

Disassembly/Reassembly
. Never use an air hose or dry brush to clean brake assemblies.
. Use an OSHA approved vacuum cleaner to avoid breathing brake dust.
. Contaminated brake discs or pads reduce stopping ability.
. When reusing the pads, always reinstallthe brake pads in their original positions to prevent loss ol braking efficiency.
CAUTION:
. Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid does contact the paint, wash it off imme-
diatelY with water.
NOTEI
. To prevent spills, cover the hose joints with rags or shop towels.
. Clean all pans in brake fluid and air dry; blow out all passages with compressed air.
. Before reassembling, check that all parts are free of dust and other foreign particles.
. Replace parts with new ones whenever specified to do so.
. Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.
. Do not reuse the drained fluid.
. Always use Genuine Honda DOT 3 Brake Fluid. Using a non-Honda brake fluid can cause corrosion and decrease the
life of the system.
. Coat the piston, piston seal, and caliper bore with clean brake fluid.
. ReDlace all rubber oarts with new ones whenever disassembled.
. After installing the front brake caliper do the following.- Check for leaks at hose and line joints and connections, and retighten if necessary.- Check the brake hoses for interference and twistinq.
