General: A complete thorough familiarization and understanding of the system and this manual is necessary before
commencing the installation. All work must conform with A.C. 43.13.1A ch. 11 sec. 2, 3, 7. The accuracy of this
instrument depends entirely upon the accuracy of the data entered. A periodical checking of the actual fuel onboard
will eliminate the accumulation of errors due to evaporation leaks, etc.
Route the (Optional) External Warning Control Line: The wire from pin 4 on the J-1 (D-SUB 9) can be
connected to an external warning light or buzzer. This pin goes to ground when the display ashes a warning. The
current in this line must be limited to 0.25 amps (maximum). Exceeding this limit will damage the unit. Tie o this wire
if not in use as not too obstruct the freedom of the controls. The FS-450 can be connected in parallel to any existing
digital fuel ow system. When connected to an existing ow sensor pin 3 red is not connected. See drawing 450508.
Install the Instrument in the Panel: Locate a 2.25 diameter hole or 3.125 diameter in the instrument panel,
where you would like to mount the indicator per drawing 450124. The instrument forcongures itself automatically
14/28 volt aircraft. The instrument is 1.5” deep less connectors and is 2.6 or 3.5 square behind the panel.
Route the Fuel Flow Transducer Wires: Route the fuel ow wires from the probes through the rewall
using reproof rubber grommets and ame retarding silicone. Use an existing hole if possible. Following the existing
wiring harness. All wires must be routed areas (exhaust stacks, turbochargers, etc.).away from high temperature
Secure Probe leads to a convenient location on the engine, being sure there is sucient slack to absorb engine
torque. It is essential in routing the fuel ow transducer wires not be allowed to touch metal parts of the air-frame or
engine since abrasion will destroy this wire. Connect wires in accordance with DWG 450508.

PN FT4-8AEXS-LEA-2029 stamped on transducer side
The placard PN 700905
"Do Not Rely on Fuel Flow Instrument to Determine Fuel Levels in Tanks.”
Must be mounted on the aircraft instrument panel near the P/N 450000( ).
If the aircraft is equipped with a primary fuel ow gage, the following placard must be mounted on the
aircraft instrument panel near the P/N 450000().
"Refer to Original Fuel Flow Instrumentation for Primary Information.”

Mount the Fuel Flow Transducer using the appropriate drawing in this manual.
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 two transducers are
required.
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). It is recommended the transducer to thenot to hard mount
carburetor or fuel servo.
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.
The ow transducer must be mounted so the wires exiting the transducer are pointing up.
Before connecting any hoses, thoroughly clean them and insure they are free of any loose material. High air
pressure my be used, However, do not allow high air pressure to pass through the ow transducer.
