The instructions listed below must be followed when installing a Fuel Flow Transducer.
Note: If your engine is equipped with a fuel return line from the carburetor back to the fuel tank you will need to install two
flow transducers... one in the feed line from the fuel pump to the carburetor and one in the return line from the carburetor back
to the fuel tank. Also, a Fuel Flow Differential Module (Dwg. 700920) will need to be installed.
The transducer output port should be mounted lower or even with the carburetor inlet port (or fuel servo on a fuel injected
engine). If this is not possible, a loop should be put in the fuel line between the Fuel Flow Transducer and the carburetor or fuel
servo (see diagram below).
Do not remove the caps on the flow transducer until the fuel hoses are ready to be installed.
The flow of fuel through the transducer must follow the direction marked on the transducer.
