6 Mounting Procedure 700923
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. Mount the Fuel Flow Transducer in the fuel line. You must use the 700900-2 Fuel Flow Transducer on a gravity
feed system. The PN 700900-2 Transducer is marked "Model 231" on the top of the transducer. The Flow
Transducer must be wrapped with Fire Sleeving 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.
4. Purchase two new hoses, one from the Fuel tank to the Fuel Flow Transducer and the other from the Fuel Flow Trans-
ducer to the Carburetor. 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.
5. For best results it is advisable to have two inches of straight tube just before the inlet to the transducer.
