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 mechanical pump to the Carburetor.
3. Remove the fuel hose which goes from the Carburetor return line to the Fuel Tank.
4. Mount the Fuel Flow Transducer in the fuel line from the mechanical pump to the Carburetor per the above drawing;
note the flow direction on the transducer. Mount the return Fuel flow transducer in the return line from the Carburetor
to the fuel tank, note the transducer will be reversed. This kit is supplied with two PN 700900-1 transducers. Check
the K factors to be within 0.1. Either transducer may be used as the supply transducer. Both Flow Transducers
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.
5. 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.
6. 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.
