Rev B : Date 03/14/97
Mounting Procedure:
1. Find a convenient location within 8" 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 to the Carburetor (or Fuel Servo).
3. Purchase two new hoses, one from the fuel pump (or the Fuel Filter) to the Fuel Flow Transducer 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 hose in the aircraft.
4. Mount the Fuel Flow Transducer in the fuel line. You must use the FXT-231 Fuel Flow Transducer on a gravity feed system.
The FXT-201 Transducer is marked "Model 231" on the top of the transducer. The Flow Transducer must be wrapped with
Fire Sleeving. Place a small hole in the fire sleeve and pass the transducer wires through it. Seal with High temperature Silicone
RTV sealant.
5. Before connecting fuel hose to the carburetor , verify that the boost pump delivers at least 125% of takeoff fuel consumption at
minimum fuel pressure as marked on fuel pressure gage.
