6-1 What comes with your diesel fuel flow sensor kit
From your Navman dealer:
Extension cables for the sensor, link and
tachometer cables.
Each diesel flow sensor kit measures
data from one engine. A second kit can be
fitted if the boat has twin engines and twin
tanks.
Filtering the fuel
The primary fuel filter will filter all particles larger
than typically 25 to 50 microns.
The clearances within the sensor are more than
100 micron, so provided there is an adequate
primary filter there will be no problems with
particles in the fuel interfering with the sensor.
If there isn’t an adequate primary filter, then
the secondary filter will be quickly blocked,
and any effects on the sensor will be the
least of the problems on the boat!. But just in
case your primary filter fails, the sensors are
equipped with a by-pass valve - one quick turn
and the entire mechanism is bypassed (see
section 1-3).
Also supplied: Self adhesive reflective tape
for tachometer, alcohol wipe for cleaning

The two sensors are distinguished by a different
coloured band around the body. The supply
line sensor has a blue band (think cooler fuel)
and the return line sensor has a red band
(think warmer fuel, after it has been through
the engine).
