Hoses and Clamps - Inspect/
Replace
Inspect all hoses for leaks that are caused by the
following conditions:
• Cracking
• Softness
• Loose clamps
Replace hoses that are cracked or soft. Tighten any
loose clamps.
NOTICE
Do not bend or strike high pressure lines. Do not in-
stall bent or damaged lines, tubes or hoses. Repair
any loose or damaged fuel and oil lines, tubes and
hoses. Leaks can cause fires. Inspect all lines, tubes
and hoses carefully. Tighten all connections to the
recommended torque. Do not clip any other item to
the high pressure lines.
Check for the following conditions:
• End fittings that are damaged or leaking
• Outer covering that is chafed or cut
• Exposed wire that is used for reinforcement
• Outer covering that is ballooning locally
• Flexible part of the hose that is kinked or crushed
• Armoring that is embedded in the outer covering
A constant torque hose clamp can be used in place of
any standard hose clamp. Ensure that the constant
torque hose clamp is the same size as the standard
clamp.
Due to extreme temperature changes, the hose will
harden. Hardening of the hoses will cause hose
clamps to loosen. This can result in leaks. A constant
torque hose clamp will help to prevent loose hose
clamps.
Each installation application can be different. The
differences depend on the following factors:
• Type of hose
• Type of fitting material
• Anticipated expansion and contraction of the hose
• Anticipated expansion and contraction of the
fittings
Replace the Hoses and the Clamps
Refer to the OEM information for further information
on removing and replacing fuel hoses (if equipped).
