Installation Note
Fuel hoses
1. Push the ends of the main fuel hose, fuel return hose, and
evaporative hoses onto the fuel tank fittings at least 25mm
(1.0 in).
2. Push the fuel filler hose onto the fuel tank pipe and filler pipe
at least 35mm (1.4 in).
FUEL FILTER
Replacement
Low-pressure side (In-tank filter)
(Refer to page F-128.)
High-pressure side
The fuel filter must be replaced at the intervals outlined in the
maintenance schedule.
Warning
l Always work away from sparks or open flames.
1. Disconnect the fuel hoses from the fuel filter.
2. Remove the fuel filter and bracket.
3. Install in the reverse order of removal.
Note
l When installing the filter, push the fuel hoses fully
onto the fuel filter.

Assembly note
O-ring set
1. Use a new O-ring set. (O-ring, cap, and spacer)
2. Apply oil or fuel to the O-ring set before installing.
3. To confirm sealing of the O-ring, blow air through the main
pipe after assembling the fuel pump and fuel tank gauge
sender unit, and verify that no air flows past the O-ring. If
air flows through the pump, the check ball may be stuck.
Shake the fuel pump two or three times and recheck.
Fuel pump
1. After installing the fuel pump to the bracket, pull the pump
down so that it is tight against the bracket.

PRESSURE REGULATOR
Inspection
Fuel line pressure
Warning
l Before performing the following operation, release
the fuel pressure from the fuel system to reduce the
possibility of injury or fire. (Refer to page F-121.)
1, Disconnect the negative battery terminal.
2. Connect a fuel pressure gauge between the fuel filter and
the fuel main hose. (Install clamps as shown.)
3. Connect the negative battery terminal.
4. Start the engine and run it at idle.
5. Measure the fuel line pressure.
Fuel line pressure:
206-255 kPa (2.1-2.6 kg/cm2, 30-37 psi)
6. Disconnect the vacuum hose from the pressure regulator
and measure the fuel line pressure.
Fuel line pressure:
265-314 kPa (2.7-3.2 kg/cm2, 36-46 psi)
