Repair or Replace?

The ingenious cam ball design that started in model 170 was simple, and proven very reliable. McFarlane has repaired many of these original Cessna valves, and we know them well. McFarlane engineers developed a new valve with several improvements to the original.

• Improved corrosion resistance
• Improved o-right retention
• More balanced fuel flow
• Fully inspected, functional, and flow tested to perform to the highest standards. 
• Our improved FAA-PMA parts save you money!

Many of the original valves have too much damage and corrosion to the main body, aluminum alloy cam, and fittings, as well as damaged o-ring retention area to effectively seal and be repaired cost-effectively.
