Fuel Flow Transducer
Adapter, (1/4" NPT to Fuel Hose) 6" Maximum from
support or fitting
Mounting Procedure:
1. Find a convenient location within 6" of a hose support or fitting and away from any hot exhaust
pipes to suspend the Fuel Flow Transducer. The hose support or fitting may be on the input or
output line of the Flow Transducer.
2. Remove the fuel hose which goes from the Fuel Pump (or the Fuel Fliter on a gravity feed
system) to the Carburetor (or Fuel Servo).
3. Purchase two new hoses: one to be used from the fuel pump (or the Fuel Filter) to the Fuel Flow
Transducer and the other to be used 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:
4. Mount the Fuel Flow Transducer in the fuel line. 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.
5. Read the Installation Instructions for important installation considerations.
