2-16 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
When removing with standard tip screwdriver:
Insert the standard tip screwdriver [A] into the slit [B] on
the joint lock [C].
Turn the driver to disconnect the joint lock.
When removing with fingers:
Open and push up [A] the joint lock [B] with your fingers.
Prying or excessively widening the joint lock ends
for fuel hose removal will permanently deform the
joint lock, resulting in a loose or incomplete lock
that may allow fuel to leak and create the potential
for a fire explosion. To prevent fire or explosion
from a damaged joint lock, do not pry or excessively
widen the joint lock ends when removing the fuel
hose. The joint lock has a retaining edge that locks
around the housing.
Pull the fuel hose joint [A] out of the delivery pipe.
Fuel is flammable and explosive under certain con-
ditions and can cause severe burns. Be prepared
for fuel spillage; any spilled fuel must be completely
wiped up immediately. When the fuel hose is dis-
connected, fuel spills out from the hose and the
pipe. Cover the hose connection with a clean shop
towel to prevent fuel spillage.
Clean the delivery pipe.
Cover the delivery pipe with the vinyl bag to keep it clean.
Remove the vinyl bag on each delivery pipe.
Check that there are no flaws, burrs, and adhesion of
foreign materials on each delivery pipe [A].
Replace the fuel hose with a new one.
Run the fuel hose correctly (see Cable, Wire, and Hose
Routing section in the Appendix chapter).
