FUEL SYSTEM
The S-7LS fuel system is a pump fed carbureted system incorporating two wing tanks ( 9
gallons each) interconnected at one fuel valve accessible to the primary occupant (front
seat).
Fuel quantity indication is provided through a fuel side gauge (clear plastic fuel line) at
each fuel tank.
The indicator is calibrated to read zero, when the unusable fuel amount
of 1.25 gall
total or 0.625 gall each tank
is reached in horizontal level flight at maximum
continuous RPM.
The ¼; ½; and ¾ marks are also with reference to level flight.
The 1 or full mark indicates a recommended refuel level, if the aircraft is to be parked
(sufficient expansion space) and is with reference to the ground attitude.
