Fuel Pipe Replacement and Identification

A fuel system pipe must fit the specified engine arrangement and use the correct connection locations. During replacement, inspect the existing pipe for damage, corrosion, deformation and signs of leakage. The replacement must match the original routing and fitting configuration.

Fuel injection systems can operate at hazardous pressures. Inspection and replacement should follow the equipment manufacturer's service procedures. Related supports, clamps and sealing components should be checked as part of the repair.
