Add to Wishlist
Part# 05-03407
MFR Model# U0411716-500


This valve has a very smooth action with positive detents. Like the original valve, it has positions for left-on, right-on and both-off. Unlike the original, it is not prone to sticking or binding. It does not require periodic seal replacement or lubrication. This PMA'd replacement valve will mount almost identically to the original OEM valve. It uses the same tank selector plate and the same mounting hardware as the original.

This valve is sold in a kit that includes the handle and installation instructions. The handle has no "pointer." This is in compliance with AD47-43-02.

Part work flawlessly

Good replacement valve for the 120/140. Worked with the o200a even though it wasn't listed on the instruction list. As the c90 and the o200a have the same data sheet. What is applicable to one is applicable to all.

Q: I have a technical question in regards to part number 05-04407(Cessna 120/140 Fuel Valve Kit). Is there an STC that goes with this part? Or, being a direct replacement for an OEM part, is an STC unnecessary?

Per the manufacturer, there is no STC. This is FAA PMAd as a direct replacement.

Q: "It does not require periodic seal replacement or lubrication." Is this guaranteed? If a leak develops, what's the procedure for warranty replacement? Thanks.

Per the supplier: We don't specify a time period for seal replacement. We have had very few ever returned for leaking, as they are pressure tested. If the valves leaks within a year, we will replace it.

Q: What is the exact distance (center to center) between mounting holes

1 inch center to center.
