Mounting Procedure:
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. Purchase two new hoses, one from the Carburetor to the Fuel Flow Transducer and the other
from the Fuel Flow Transducer to the Fuel Tank. There must be flexible hose in and out of
the Transducer. The hoses must meet TSO-C53a Type C or D FAA specification. The new
hoses must be the same diameter as the current hose in the aircraft. A source of fittings
and fabricated hoses is:

or Herber Aircraft

El Segundo, CA 90245 (310) 322-9575
4. Mount the Fuel Flow Transducer in the fuel supply line and in the return line for pressure
carburetors. The Flow Transducer must be wrapped with Fire Sleeving. Place a small hole
in the fire sleeve and pass the transducer wires through it. Seal with High temperature Silicone
RTV sealant.
5. 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.
