Fuel Tube/Quick-Connect Fittings
Precautions
Do not smoke while working on the fuel
system. Keep open flames away from your work area.
The fuel tube/quick-connect fittings assembly connects
the in-tank fuel pump with the fuel feed pipe. For remov-
ing or installing the fuel pump and fuel tank, it is neces-
sary to disconnect or connect the quick-connect fittings.
Pay attention to following:
• The fuel tube/quick-connect fittings assembly is not
heat-resistant; be careful not to damage it during
welding or other heat-generating procedures.
• The fuel tube/quick-connect fittings assembly is not
acid-proof; do not touch it with a shop towel which
was used for wiping battery electrolyte. Replace the
fuel tube/quick-connect fittings assembly if it came
into contact with electrolyte or something similar.
• When connecting or disconnecting the fuel tube/
quick-connect fittings assembly, be careful not to
bend or twist it excessively. Replace it if damaged.
A disconnected quick-connect fitting can be reconnected,
but the retainer on the mating pipe cannot be reused
once it has been removed from the pipe. Replace the
retainer when
• Replacing the fuel pump.
• Replacing the fuel feed pipe.
• It has been removed from the pipe.
• It is damaged.
