Installation and Operation Manual
36
Calibrate petrol/gasoline fuel flow sensors
during installation, or if the fuel readings seem
inaccurate and the other troubleshooting
suggestions do not help (see appendix B
troubleshooting).
Note
SmartCraft fuel sensors are factory calibrated
and should never need recalibrating.
On a multi engine boat, calibrate each
engine’s sensor. This can be done at the same
time with a portable tank for each engine or
at different times using one portable tank.
Calibrating a sensor requires accurate
measurement of the fuel consumption.
This is best done using a small portable tank.
At least 4 gallons (15 litres) of fuel should be
used to ensure an accurate calibration.
It is often very difficult to fill underfloor tanks
to the same level twice due to air pockets, so
the more fuel used, the more accurate the
calibration.
7-7 Calibration
To calibrate the sensor(s):
1 Record the level of the fuel in the tank(s).
2 Connect the portable tank(s) to the engine
through the fuel sensor(s).
3 Run the engine at normal cruising speed until
at least 4 gallons (15 litres) of fuel has been
used per engine.
4 Check the actual amount of fuel used per
engine by refilling the portable tank(s) to the
original level and noting the reading(s) of the
fuel dispenser’s gauge.
5 Press
twice, select
Fuel
then select
Setup engines
.
6 On a single engine boat, select
Calibrate
and change the displayed value to be equal
to the reading of the fuel dispenser’s gauge,
then press
.
On a multi-engine boat select the engine.
Select
Calibrate
and change the
displayed value to be equal to the reading of
the fuel dispenser’s gauge, then press
.
Repeat for the other engines.
