P/N: 0700099-3 / 0700099-10
Part Number: 0700099-3 / 0700099-10
Part Name: Line Assembly – Primer (Primer Pump to Firewall)
Aircraft: Cessna 185 / 185F Skywagon
Manufacturer: Cessna Aircraft Company
System: Engine Fuel Primer System
Condition: Used / Sold As Removed (or adjust to your condition)
This listing is for a Cessna primer line assembly used on the Cessna 185F Skywagon, part numbers 0700099-3 and 0700099-10. This rigid fuel line assembly is part of the aircraft engine primer system and routes fuel from the primer pump to the firewall or primer distribution fitting.
The primer system is used during engine start procedures to deliver a small amount of fuel directly into the engine intake system. This assists with cold starting and initial engine combustion, particularly in piston aircraft equipped with Continental engines.
The line assembly is constructed from aircraft-grade aluminum tubing with flared fittings, designed to withstand aviation fuel exposure, engine compartment temperatures, and vibration loads encountered during normal aircraft operation. The line is pre-formed at the factory to ensure correct routing and installation within the aircraft fuel system.
This component is commonly found in Cessna 180, 182, and 185 series aircraft, including the C185F, which typically uses the Continental IO-520 engine configuration.
