Supersedes Service Bulletin No. 342F

MODELS AFFECTED

All fuel injected Lycoming engines indicated in fuel line and clamping diagrams.

TIME OF COMPLIANCE

Examine fuel lines every 100 hours, annual inspection, overhaul and any time fuel lines or clamps are serviced, removed, or replaced.

This Service Bulletin contains procedures for installation, inspection, and corrective action of fuel lines on fuel injected engines. Each fuel line must be installed with support clamps to keep the fuel lines securely located in place to prevent tube damage due to vibration and rubbing against other parts of the engine. Vibration, rubbing, and/or kinks in the fuel lines can cause cracks in the fuel lines, loss of fuel, and a fire.
