Device desctription
This device is useful for a motorcycles (and ultralight aircrafts, excavators, tractors etc.)
without the built-in float in the tank. LSK FuelGaugePro2 is easy to setup for a wide range of fuel
tanks. It's function is based on measuring of the hydrostatic pressure of the fuel. Advantage of this
principle is minimal installation intervention (no need to make any holes into the fuel tank). Fuel
gauge is connected to the fuel hose via supplied T-shape plug. Fuel Gauge device is divided into
2

two units, sensor unit and display unit. The universal fuel gauge must be calibrated before using.
The working principle not allows to connect the gauge to hose, into which the fuel is drawn by the
fuel pump.
•It cannot be used on bikes without on-board battery. The electricity from the generator is too
unstable, causing the protection to shut down the gauge.
•The gauge is connected to the fuel hose from the tank using a plastic T-shape three way
connector. It must be placed really under the fuel tank.
•The fuel gauge does not work when it is connected to a pipe, into which the fuel is delivered
by a fuel pump (It can be used if the motorbikes is equipped with some types of external
fuel pump, it is explained in this document below).
•If the fuel gauge is connected under a vacuum controlled fuel cock, that needs to work just
fine and not remain partially closed.
•It only works on bikes with a 12 volt electrical system. It does not work on 6 volts. This can
be solved by a 6V/12V converter that can be purchased in our website. In case of need, we
will help with any uncertainties.
•It can be used on other machines, including diesel powered, like tractors, excavator etc.
•The fuel tanks with fuel evaporation control (Active charcoal filter) may cause problems
with hydrostatic measurement principle.

Answers on FAQ
•The gauge is not affected with fall of the bike on the ground.
•The fuel gauge has linear measuring. Every bar means a twelfth of the amount of fuel or a
twelfth of the pressure generated by the fuel. The showed decline in the fuel amount is
therefore absolutely steady.
•The gauge doesn't lose its memory after being disconnected from power. The data is stored
in a FLASH memory that can last years without power.
•The gauge or the sensor do not suffer in rough environment. The terrain change
compensation will work very well here too.
•Even when the gauge is broken, the motorcycle can't be affected by this – only if you rip
your fuel hose off and the fuel starts to leak.

Usage restrictions
Fuel Pump: External Fuel Pump: Fuel Tank Air Intake:
CAUTION: We cannot guarantee the correct function on all motorcycles with a fuel pump. The
external fuel pump may cause problems with measuring on some motorcycles. If this problem
occurs, you can return FuelGauge to us and we will return your money back to you. Device must be
in intact condition.

Device mounting
Find a suitable place for the sensor
It can be over or under the fuel tank. It is better to mount it under the fuel tank and fill the
hose up with fuel. This will make the gauge the most accurate.
•Do not place the unit on hot places. It can handle temperature up to 60°C(140°F).
•Check, if the display can reach your desired spot (if the cable is long enough).
•If you can, connect the gauge to the hose between the fuel tank and the fuel cock (not
necessary, see picture below).
•The sensor unit can be in any position (lying or even with the fuel hose going up).

Electrical parts connection
Pressure sensor: See previous chapter „Find a suitable place for the sensor “.
Display: Pick a suitable place and secure it. If you decide to use tape, clean the surface before
mounting the display (using degreasing agent – ethanol or other).
Supply leads: Connect over the ignition switch, then the gauge will be switched on together with
the ignition key.
(-) Black cable: The best way to connect the (-) pole is to use the ring tongue terminal and
screw it on some place of the frame, or even to the (-) pole of the battery. It can be also attached to
any other (-) wire (usually black) using the cut in connector included in the package, but you must
be 100% sure it is a (-) wire.
(+) Red cable: Use the cut in connector to connect it to another (+) cable that is switched on
with the ignition. You can observe that by trying the gauge with its (+) cable on (+) cable of the
motorcycle, while switching the ignition key on and off. It is always better however to leave this to
a trained technician, who will do it professionally. This will prevent future problems with supply
voltage, because cut in connector doesn't ensure 100% durable contact.

Connect the gauge to the fuel hose
Connection should be made according to the two pictures on previous page. Do not forget to
secure the hoses with the clips included in the package. Check the system for any fuel leaks after a
few kilometres and also after longer distances periodically. If everything is right and the gauge
works, you may proceed to the setup.
Fuel gauge setup
Measuring modes
Min max mode: This mode is usable for easy and quick calibration. For this mode is
required to measure only 2 fuel levels, minimal level and full fuel level. The LED segments lights
in linear dependence on fuel level (height of fuel in the tank).
Auto-calibration mode: In this mode, the device is displaying real amount of the fuel even
if the fuel tank shape is very varied. This mode is more difficult to set than "min/max" mode.
Device settings
1) Calibration settings
Empty tank level: Save this value when fuel tank is empty. Set this value when min/max
mode will be used.
Full tank level: Save this value when fuel tank is full. Set this value when min/max mode
will be used.
Auto-calibration process (experimental):
1) Fuel tank must be full. Prepare a jerry can for leaking fuel during calibration.
2) Remove the tank cap.
