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 Carburetor to the Fuel Tank.
3. Purchase two new hoses, one from the Carburetor to the Fuel Flow Transducer and the other from the Fuel Flow Transducer to the
Fuel Tank. 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 diameter as the current hose in the aircraft.
4. Mount the Fuel Flow Transducer in the fuel supply line and in the return line for pressure carburetors. 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.
