DFI Servicing Precautions
To prevent corrosion and deposits n the fuel system, do
not add any fuel antifreeze chemicals to fuel.
When any fuel hose is disconnected, do not turn on the
ignition SW. Otherwise, the fuel pump will operate and
fuel will spout from the fuel hose.
Do not operate the fuel pump if the pump is completely
dry. This is to prevent pump seizure.
Before removing the fuel system parts, blow the outer sur-
faces of these parts clean with compressed air.
When any fuel hose is disconnected, fuel may spout out
by residual pressure in the fuel line. Cover the hose joint
with a piece of clean cloth to prevent fuel spillage.
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
Routing section in the Appendix chapter.
When installing the fuel hoses, avoid sharp bending, kink-
ing, flattening or twisting, and route the fuel hoses with a
minimum of bending so that the fuel flow will not be ob-
Replace the hose if it has been sharply bent or kinked.

tion shown, and securely tighten the clamp screws to the
specified torque. Check the fuel system for leaks after
