G. FUEL FILLER CAP:
The fuel tank filler neck has a vented Fuel cap. Inside the fuel filler cap is a pressure release valve. This allows it
to vent the fumes in and out from fuel tank if they build up to predetermined levels. The fuel filler cap has O’ ring
around the neck. This O’ ring should be inspected for cracks or inflexibility. If the O’ ring become cracked or
inflexible, it should be replaced to keep the environment clean. A ratchet tightening device on the threaded fuel filler
cap reduces the chances of over tightening and incorrect installation. After the ‘O’ ring on fuel filler cap and the fuel
filler neck flange contacts, the ratchet produces a loud clicking sound, indicating the seal has been set.
REMOVAL / INSPECTION:
1. Remove fuel filler cap.
2. Check O ring for even filler neck imprint.
3. Check O ring for any deterioration or any damage.
If found damaged replace fuel filler cap.
4. Check vent mechanism by simply applying mouth
air pressure at threaded cap. For any deterioration
or any damage in vent mechanism replace fuel filler
cap.
NOTE :
IN CASE OF FUEL FILLER CAP, REPLACEMENT
TO BE DONE WITH CORRECT CAP. OTHERWISE
IT MAY RESULT IN CRITICAL MALFUNCTION OF
THE SYSTEM.
H. FUEL HOSES & LINES:
The delivery and return lines are made of nylon pipes
with quick fix couplings at joints.
REMOVAL:
1. Disconnect the quick fix couplings by pressing the
two tabs from the lines.
INSPECTION:
1. Visually check all hoses and pipes connected via
clamp and quick connectors for leaks, loose con-
nections, deterioration or damage, hose crack etc.
Replace if necessary.
2. Make sure that all clamps and quick connectors
are secure.
3. If the pipe clamps found deformed, bent or broken,
replace with new one.
FILLERASSEMBLY:
1. Do not tighten the clamps used on filler hose ex-
cessively to avoid damage to hoses.
2. Fuel hoses to filler pipe vary for each type of pipe.
Necessary care to be taken to connect and clamp
each hose correctly.
3. Do not kink or twist hose / pipe when they are routed.
4. Connect negative terminal at battery.
5. Turn ignition switch ON and run engine idle. Check
for fuel leakages.
