The 491-960 Fuel Selector Valve (Overhauled) is a critical fuel system component used in Piper aircraft, allowing the pilot to select between different fuel tanks or shut off fuel flow entirely. This unit has been overhauled, meaning it has been disassembled, inspected, repaired as necessary, and restored to serviceable condition in accordance with aviation maintenance standards.

The valve ensures controlled and reliable fuel routing from the selected tank to the engine, maintaining proper fuel supply during all phases of flight.

Its primary functions include:

Allowing selection between multiple fuel tanks
Controlling and directing fuel flow to the engine
Providing shutoff capability for safety and maintenance

Overhauled fuel selector valves like the 491-960 are essential for safe aircraft operation, ensuring reliable fuel management while meeting regulatory airworthiness requirements through certified overhaul processes.
