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).
2. 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. A source of fittings and fabricated hoses is:

4. Mount the Fuel Flow Transducer in the fuel line. The FXT-201 Transducer is marked "Model
201" 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.
