FUEL LINE / HOSE
QUICK DISCONNECT SERVICE
When removing the fuel line, follow these steps to avoid
damage to the components:
1. Always thoroughly clean the fitting from both sides.
Grit can become lodged between the nipple and the
collar of the line, making it difficult to move the tabs of
the collar. Use air first, then water if necessary to
flush the fitting.
NOTE
Avoid using lubricants. It will damage the seals in the
fitting, and also will retain and attract dirt, making it
more difficult to dislodge the retaining collar.
2. Gently push outward and back on the retaining collar.
Only spread the ears
q
of the collar far enough to
allow the collar to move back.
3. Have a shop towel prepared to clean the fuel that will
be spilled when removing the fuel line.
4. When installing, ensure that the collar is fully
installed.
5. Gently pull on the line to ensure it is fully seated.
6. Cycle the ignition key to prime the pump, and ensure
there are no leaks before re-assembly.
