Mounting Procedure: 700922

1. Find a convenient location between the Throttle Body and the Flow

Divider and away from any hot exhaust pipes to suspend the Fuel Flow
Transducer.

2. Remove the fuel hose which goes from the Throttle Body to the Flow

Divider.

3. Purchase two new hoses, one from the Fuel Servo to the Fuel Flow

Transducer and the other from the Fuel Flow Transducer to the Flow
Divider. There must be flexible hose in and out of the Fuel
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. The Flow Transducer

must be wrapped with Fire Sleeve

available at JPI.

Place a small

hole in the fire sleeve and pass the transducer wires through it. Seal
with High temperature Silicone RTV sealant.

5. Secure at either end of the transducer to any convenient point on the engine with MS21919 clamps or

equivalent.

6. For Continental fuel injected engines adjust the fuel pressure to account for the pressure drop across the

transducer per Continental Service Bulletin M89-10,

available at JPI.
