Num tanks
Set the number of fuel tanks. If there are two

Setup engines
If the boat has more than one engine, select
Engine and select each engine in turn.
For the selected engine, you can enter:
From tank:
The fuel tank the engine is
connected to.
Flow filter:
Most engines do not draw fuel
from the tank at a steady rate. To give a stable
fuel flow reading, the 8120/8084 calculates
the flow by taking several measurements and
averaging them. Use the Flow filter to set the
period over which the fuel flow is averaged.
The Flow filter can be set from 0 to 30
seconds. Use the lowest value which gives a
stable flow.Usually a value of 5 to 10 seconds
will give a satisfactory result for two-stroke
carburetor engines. Fuel injected or four-
stroke engines may require a larger value.
This setting affects the Fuel flow and Fuel
economy reading on the Fuel display but it
does not affect the Fuel used reading.
Setup tanks
If the boat has more than one tank, select
Tank and select each tank in turn.
For the selected tank, you can enter:
Tank size:
The tank capacity. NAVMAN
recommends measuring tank size by draining
the fuel tank, filling it to capacity and using
the fuel dispenser’s reading. Beware of air
pockets, especially in underfloor tanks.
Fuel alarm:
See section 13-4.
