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.

If the transducer is
higher than the
carburetor or fuel servo,
put a loop in the fuel line
between the transducer
and the carburetor or
fuel servo.
