Product Details

Note: McFarlane has limited ability to repair the 108HD1/4X1/4X1S valve, as parts for this valve are no longer available. Core credit can only be issued for a core that is within full repairable limits.



Repaired Fuel Selector and Fuel Shut-Off Valves 

New Cessna Fuel Valves also available!


To qualify for a core charge refund, the major components of the core you return must be in a serviceable condition. We can also repair your valve - Please call 866-920-2741 for a quote and more information.


Some Cessna fuel valves require special tools and processes for reassembly. For your convenience, McFarlane also offers repaired fuel valves. We can repair your valve or you can purchase one from our inventory and then return yours for core credit. McFarlane has many valve part numbers in stock and ready to ship.


Repaired fuel valves are cleaned, inspected and assembled with all new seals, gaskets, hardware and parts as required. Each valve is repaired by our experienced A&P technicians and pressure tested for leaks and evaluated for proper fuel flow. You will receive a "Return to Service" tag to certify the repair.


Now for more good news!!

All of the improved parts that go into our new valve are interchangeable with the original Cessna valve. This means that if your valve is good with the exception of a few parts, we can fix it at a reasonable price! Whether you need your valve repaired or a new valve, McFarlane will save you money.

From years of experience, McFarlane found flaws that degrade the service life and repairability of the original cessna valves.

We directly address these issues in our improved design to provide a higher quality, longer lasting valve.

Why not just repair my valve?

Many of the original valves have too much damage to be repaired cost-effectively. The original Cessna fuel valve that started in model 170 was a simple but ingenious cam ball design that has proven very reliable over the years. McFarlane has repaired a lot of these original Cessna valves, and we know them well. However, we are now rejecting a big percentage of the valve cores sent to us. A lot of them have corrosion damage in the main body that is too severe to fix, or the O-ring retention area is damaged and too rough to seal. Many of the fittings are corroded through. The cam bearing is brass and easily corrodes the aluminum alloy cam. 


Proven Design with Improvements

Improved corrosion resistance: McFarlane’s new valves are totally anodized where the original valves were Alodine conversion coated. This change drastically improves the surface durability, wear resistance, and corrosion resistance of all the components, and they will stay pretty too! Corrosion protection is important since the valves are at the lowest point in the fuel system without any upstream water separation or contaminate screening. We have also eliminated the brass bushing that corrodes the cam.


Improved O-ring retention: Modern machining processes lets us precision machine the O-ring capture cavity. The original valve O-rings were retained by staking (stamp forming) the housing. This process was inconsistent at best and distressed and weakened the surrounding aluminum structure.


More balanced fuel flow: Yesterday’s manual machining process of the original valves were often inconsistent enough to let one port flow more fuel than needed while the other port might flow a very marginal amount of fuel. The new McFarlane valve is computer machined for a perfect balance of fuel flow.


Fully Tested

You can rest assured that if it’s a new McFarlane valve or a valve repaired by McFarlane, it will be pressure, functional, and flow tested to perform to the highest standards.

Maintenance Tip!
The fuel selector valve works in unscreened fuel. Contaminated fuel can cause selector valve seal damage. When fueling from possibly contaminated fuel sources, McFarlane recommends the use of a micro-screened funnel, such as Mr. Funnel.



  • Detent housing, handle, cam, detent plate, tube fittings, and/or drain fitting must be sent with the body of the valve as applicable to your valve.
  • The "S", "SF", or "SP" suffix indicates a McFarlane repaired valve. The applicable Cessna P/N is the McFarlane P/N without the suffix. Reference the Cessna P/N for all maintenance procedures. 
  • 0513120 series valves: McFarlane will request your signature stating compliance with AD# 99-27-02. Please call 866-920-2741 for more information.
  • 0716613 series valves: These valves require a special tool and process for reassembly. Each valve is repaired using an FSO-KT-1 repair kit by an A&P mechanic and fully leak tested. You will receive a "Return to Service" tag to certify the repair.
