DFI Servicing Precautions
The fuel hoses are designed to be used throughout the
motorcycle's life without any maintenance, however, if the
motorcycle is not properly handled, the high pressure in-
side the fuel line can cause fuel to leak [A] or the hose to

Replace the fuel hose if any cracks [B] or bulges [C] are
Route the hoses according to Cable, Wire, and Hose

minimum of bending so that the fuel flow will not be ob-
Replace the hose if it has been sharply bent or kinked.
Install the hose clamps in the position shown, and se-
curely tighten the clamp screws to the specified torque.
