FUEL BAY QUICK-DRAIN VALVE KIT
Two fuel bay quick-drain valves and a fuel sampler cup are
available as a kit to facilitate daily draining and inspection of fuel
in the fuel bays for the presence of water and sediment. The valves
replace existing fuel bay drain plugs located at the lower inboard
area of the wing. The fuel sampler cup, which may be stowed in
the map compartment, is used to drain the valves. The sampler cup
has a probe in the center of the cup. When the probe is inserted into
the hole in the bottom of the drain valve and pushed upward, fuel
flows into the cup to facilitate visual inspection of the fuel. As the
cup is removed, the drain valve seats, stopping the flow of fuel.
OIL QUICK-DRAIN VALVE
An oil quick-drain valve is optionally offered to replace the
drain plug in the oil sump drain port. The valve provides a quicker
and cleaner method of draining engine oil. To drain the oil with this
valve installed, slip a hose over the end of the valve, route the hose
to a suitable container, then push upward on the end of the valve
until it snaps into the open position. Spring clips will hold the valve
open. After draining, use a screwdriver or suitable tool to snap the
valve into the extended (closed) position and remove the drain hose.
