The F391 flush valve from MDI Aerovalve is used as original equipment by most aircraft manufacturers and has been FAA/PMA approved for replacement parts.
This flush fuel drain valve is designed to be practical, functional, and inexpensive. The head of the valve does not extend beyond the wing to catch the door of your airplane or to hit your head as you walk beneath it. Fuel is only released when you want it to be with the use of our F391 fuel sampler cup, not all over your arm or in your eyes on a windy day.
