To the Carburetor
(or Fuel Servo)

Fuel Flow Transducer

Adapter, (1/4" NPT to Fuel Hose)

6" Maximum from
support or fitting.

Mounting Procedure:

1. Find a convenient location within 6" 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 and the support may be to an adjacent hose.

2. Remove the fuel hose which goes from the Fuel Pump (or the Fuel Filter on a gravity feed system) to

the Carburetor (or Fuel Servo).

3. Purchase two new hoses: one to be used from the fuel pump (or the Fuel Filter) to the Fuel Flow

Transducer and the other to be used from the Fuel Flow Transducer to the carburetor (or Fuel
Servo).

There must be flexible hose in and out of the Transducer.

The hoses must meet TSO-

C53a Type C or D FAA specifications.

The new hoses must be the same size as the current

hoses in the aircraft.

Sources of fittings and fabricated hoses are:

4. Mount the Fuel Flow Transducer in the fuel line.

You must use the FT-90 (Gold Cube) Fuel

Flow Transducer on a gravity feed system or for any engine over 350 H.P.

If the Trans-

ducer is mounted within 6" of an exhaust pipe, the Flow Transducer must be wrapped
with Fire Sleeving.

5. Read the Installation Instructions for important installation consider-
