system servicing information.
FUEL SELECTOR VALVE.
The rotary-type fuel selector
valve
has three positions, labeled
"
BOTH
OFF,"
"LEFT
ON" and "RIGHT ON.
"
The
"BOTH
OFF" pOSition seals
both wing tanks off from the rest of
the fuel system and allows no fuel
to pass beyond the selector valve.
The "LEFT ON" position provides
fuel flow from the left tank to the
engine. Similarly, the "RIGHT ON"
pOSition provides flow from the right
tank to the engine. Both the fuel feed
and
vapor
return lines for each tank
go
throogh the selector
valve,
so that
fuel returns to the tank from which
it
is
drawn. Fuel cannot be us
ed
fro"1
both tanks simultaneoosly.
