6C-14  ENGINE FUEL (C24SE) 
Removal 
CAUTION:  When repair to the fuel system has been
completed, start engine and check the fuel system
for loose connection or leakage. For the fuel system
diagnosis, see Section “Driveability and Emission".
1.  Disconnect battery ground cable. 
2.  Loosen slowly the fuel filler cap. 
NOTE: To prevent spouting out fuel to change the
pressure in the fuel tank. 
NOTE: Cover opening of the filler neck to prevent any
dust entering. 
3.  Jack up the vehicle. 
4.  Support underneath of the fuel tank with a lifter. 
5.  Remove the inner liner of the wheel house on rea
r
left side. 
6. Remove fasten bolt to the filler neck from the
body. 
7. Disconnect the quick connector (8) into the fuel
tube from the fuel pipe and the evapo tube from
evapo joint connector. 
NOTE: Cover the quick connector to prevent any dus
t
entering and fuel leaking. 
NOTE: Refer to “Fuel Tube/Quick Connector Fittings” in
this section when performing any repairs. 
8.  Remove fasten bolt (1) to the tank band and the
tank band (2). 
9. Disconnect the pump and sender connector on the
fuel pump and remove the harness from weld clip
on the fuel tank. 
10. Lower the fuel tank (6). 
NOTE: When the fuel tank is lowered from the vehicle,
don’t scratch each hose and tube by around other pars.
 
 
Installation 
1.  Rise the fuel tank into position. 
NOTE: Ensure hoses and tubes do not foul on othe
r
component. 
2. Connect the pump and sender connector to the
fuel pump and install harness to into the plastic clip 
welded to the top of the fuel tank.. 
NOTE: The connector must be certainly connected
against stopper. 
Ensure tank band anchor mates with guide hole on
frame. 
3.  Install the tank band to fasten bolt. 
Torque: 68 N
 m (6.9kg
 m/50 lb ft) 
NOTE: The anchor of the tank band must be certainly
installed to guide hole on frame. 
4. Connect the quick connector from the fuel tube to 
the fuel pipe and the evapo tube from evapo join
t 
connector. 
NOTE: Pull off the left checker into the fuel pipe. 
NOTE: Refer to “Fuel Tube/Quick Connector Fittings” in
this section when performing any repairs. 
5.  Install the filler neck to the body by bolt. 
6.  Install the inner liner of the wheel house on rea
r 
side. 
7. Remove lifter to support underneath of the fuel
tank. 
8. Put back the vehicle. 
9. Tigten the filler cap until at least three clicks are 
heard. 
10. Connect the battery ground cable.

0A-2  GENERAL INFORMATION 
GENERAL REPAIR INSTRUCTIONS 
1. Park the vehicle on level ground and chock the front or rear wheels before lifting the vehicle. 
2. Raise the vehicle with a jack set against the axle or the frame. 
3. Support the vehicle on chassis stands. 
4. Use covers on the vehicle body, seats, and floor to prevent damage and/or contamination. 
5. Disconnect the grounding cable from the battery before performing service operations. 
 
This will prevent cable damage or burning due to short circuiting. 
6. Handle brake fluid and antifreeze solution with great care. 
 
Spilling these liquids on painted surfaces will damage the paint. 
7. The use of the proper tool(s) and special tool(s) where specified is essential to efficient, reliable, and safe 
service operations. 
8. Always use genuine ISUZU replacement parts. 
9. Discard used cotter pins, gaskets, O-rings, oil seals, lock washers, and self-locking nuts at disassembly. 
  Normal function of these parts cannot be guaranteed if they are reused. 
10. Prepare new cotter pins, gaskets, O-rings, oil seals, lock washers, and self-locking nuts for installation. 
11. Keep the disassembled parts neatly in groups. 
This will facilitate smooth and correct reassembly. 
12. Keep fixing nuts and bolts separate. 
Fixing nuts and bolts vary in hardness and design according to installation position. 
13. Clean all parts before inspection or reassembly. 
14. Clean the oil ports and other openings with compressed air to make certain that they are free from dirt and 
obstructions. 
15. Lubricate the rotating and sliding faces of all moving parts with oil or grease before installation. 
16. Use the recommended liquid gasket to prevent leakage. 
17. Carefully observe all nut and bolt torque specifications. 
18. When removing or replacing parts that require refrigerant to the discharged from the Air conditioning system, be 
sure to use the Vehicle Refrigerant Recovery and Recycling Equipment (VRRRE) to recover and recycle R134a, 
to promote the movement for the protection of the ozone layer covering the earth. 
19. Check and recheck your work.  No service operation is complete until you have done this.

Side Plate 
The sliding faces of parts must be free from step wear
(more than 0.01 mm), which can be felt by the finger
nail. The parts with minor scores may be reused after
lapping the face. 
 
Valve 
The sliding face of the valve must be free from burrs
and damage. The parts with minor scores may be
reused after smoothing with emery cloth (#800 or finer).
 
Shaft 
Oil seal sliding faces must be free from a step wear
which can be felt by the finger nail. Needle bearing fitting
face must be free from damage and wear. 
 
O-ring, Oil Seal, Retaining Ring 
Be sure to discard used parts, and always use new
parts for installation. Prior to installation, lubricate all
seals and rings with power steering fluid. 
 
Pressure Switch 
Check the switch operation as follows: 
With engine idling and A/C on, turn the steering wheel
fully to the left; compressor should interrupt and engine
idle speed will increase. Shut off A/C and again turn
steering fully to the left; engine idle will increase. I
f
system fails to function properly, disconnect connector
at the pressure switch and repeat system check while
testing continuity across disconnected SW connector. 
 
Reassembly 
1.  Install oil seal to front housing. Be sure to discard
used oil seal, and always use new parts fo
r
installation.
