Locate the two sensors and the
tachometer reasonably close together
to allow for neat and tidy cable
routing. Supplied with the sensors
are the sensor cable (20 m (65 ft));
the link cable (2 m (6 ft)) and the
tachometer cable (4 m (13 ft)).
Extension cables are available for all
of these cables.
7-3 Planning where the parts of the kit will be fitted
Plan where all the parts will be located before starting to install the parts.
7-3-1 Overview
Mount the fuel
flow sensor
horizontally
Allow for easy
access to plug
and unplug the
cables.
Bypass valve.
Allow for easy access to the bypass valve
Do not install the sensor
where it will get wet from
water in the bilges.
7-3-2 Mounting a sensor
Attach the sensors firmly to
a vertical panel or mounting
block on the boat. While
the sensors are not heavy,
they should not be left
hanging from the pipework.
Over time vibration and
heavy pounding from rough
seas could lead to the fuel
lines fracturing, with tragic
consequences.
