gravity feed system).
Mounting Procedure:
1. Find a convenient location on the fire wall (away from any hot exhaust pipes) and mount a
bracket for the Fuel Flow Transducer. Check both sides of the fire wall for clearance before
drilling any holes.
2. Mount the Fuel Flow Transducer onto the Bracket. You must use the FT-90 Fuel Flow Trans-
ducer on a gravity feed system or for any engine over 300 H.P. The FT-90 Transducer is
marked "Model 231" on the top of the transducer. If the Transducer is mounted within 6" of an
exhaust pipe, the Flow Transducer must be wrapped with Fire Sleeving.
3. Remove the fuel hose which goes from the Fuel Pump (or the Fuel Filter on a gravity feed
system) to the Carburetor (or Fuel Servo).
4. Purchase two new hoses, one from the fuel pump (or the Fuel Filter) to the Fuel Flow Transducer
(making provisions for the fuel pressure transducer as necessary) and the other from the Fuel
Flow Transducer to the carburetor (or Fuel Servo). There must be flexible hose in and out of
the Transducer. The hoses must meet TSO-C53a Type C or D FAA specification. The new
hoses must be the same size as the current hoses in the aircraft. A source of fittings and
fabricated hoses is:
