Assembly
Note
•
The assembly procedure differs depending on whether the fuel filter (high-pressure) and fuel pump are
replaced as a single unit or replaced separately.
•
Perform Step 1 (type B, C).
•
Go to Step 7 (type A).
Type B, C
Caution
•
Be careful not to damage the O-ring or
seal rubber. If it is damaged, a seal
malfunction may occur causing a fuel
leakage.
1. Apply clean oil to the new O-ring and seal rubber.
2. Install the O-ring in the position shown in the
figure for the fuel pump, being careful not to twist
it.
3. Install the spacer and seal rubber to the fuel
pump discharge pipe. Verify that the lower case is
not split, chipped, or bent.
Caution
•
Hold the fuel pump in the upright
position and insert it from the bottom side, being careful not to apply load to the fuel filter (low-
pressure). If load is applied to the fuel filter (low-pressure), it may cause the filter to dislocate or
tear.
•
Install the O-ring in the upright position.
If it is not in the upright position, fuel
pump vibration may be transmitted to the
fuel filter (high-pressure) causing noise
inside the vehicle.
4. Hold the fuel pump in the upright position and
insert it into the fuel filter from the bottom side
being careful not to twist the O-ring.
