First I want to thank you to for buying the iFuel fuel gauge.
I hope you’ll enjoy using it.
It makes flying a bit more fun just by knowing how much fuel you really have instead of an estimate.

Screen Layout:
Upper button is Button A.
Lower button is Button B.
Screens are equal on both devices.
Main Screen 
On the main screen you’ll find your current fuel level as a graph, percentage and amount.
Also you can see your current fuel usage in L/H.
And also Estimated Time Left (ETL);
Screen 2 
On screen 2 you can see some statistics.
– Current fuel usage in L/H.
– Average fuel usage over total trip in L/H.
– Fuel used during trip in ml.
– Trip Runtime.
Screen 3 
On screen 3 you can see some statistics.
– Fuel Left in tank in ml.
– Fuel used during trip in ml.
– Estimated Time Left.
– Trip Runtime.
Screen 4 
On screen 4 you can Set your tank level.
Set your tank level by pressing button B once to go into edit mode.
Then press button A with 0.25l increments.
To save your tank level, press button B once.
Screen 5 
On screen 5 you can Set your tank size. )( only on Main unit. )
This has only to be done the first time.
Or if you mount it to a another machine.

On screen 6 you can see The battery level. ( On main unit.)
On the Display Unit it show the Main unit battery in percentage level AND in the right
corner, the level from the Display unit in Volts. ( 100% 4.2 volts, 0% is 3.2 volts.
The main indicator for charging is the blue light inside the housing.
If blue light is on inside the housing, the battery is charging. ( not always displayed perfectly on screen.)

Installation:
Best way to place sensor is Vertical with input on the bottom of the sensor! It’s the best way to get all the air out after it has been sitting for a while. If Air gets trapped in the sensor, there could be some false readings! That’s why my recommendation is to mount it Vertical with input at bottom!
- Cut the fuel line just above the tank.
Try to mount it as close as possible to your tank output, far away from the engine. ( If mounted to close, there’s is a chance for electric interference from the ignition coil.)
In case of a dried fuel line, replace your fuel line with a new one.
The fuel line should have an inner diameter of 5.85 to 6 mm.
If your fuel line has an inner diameter of 8 mm i suggest to cut 2 pieces of 6 mm inner and 8 mm outer tube just a bit longer than the in- and output on the sensor. After that just press it in you 8 mm inner tube. ( don’t worry about flow!! This sensor is capable of 66 L/H!)
- Route cable to the spot where you want to have your display. Don’t route cable close to the ignition lines.
- Insert sensor into the fuel line with the correct direction.
There’s an arrow on the sensor that indicates the direction of the fuel flow. ( Doesn’t show up on photo.)
The Thicker part ( right side )of the sensor is the Input, coming from the Fuel Tank. ( see picture > ).
- Fix the main unit on the designated spot on your frame or Fuel tank with double sided fuel resistant 3M foam tape or Velcro.
Usage:
- First Time Use:
the first time you start up your fuel gauge you’ll have to enter your tank size into the Main unit.
You’ll find the setting for the Tank Size on screen 5.
- Press button A until you are on the ‘Tank Size’ screen.
- Press button B, 1 time to go to set mode.
- Set your Tank Size by pressing button A with 0,25 L increments.
- Save your Tank Size press button B, 1 time.
You can always come back to the menu and change the size of the Fuel Tank.
- Normal use:
Before every flight you should enter the correct amount of fuel in the tank. ( Only after refueling ! Old level will be saved When you turn off the device. )
And make sure both iFuel devices are charged before flight!
You’ll find the setting for the Tank Level on screen 4.
- Press button A until you are on the ‘Tank Level’ screen.
- Press Button B to go into set mode.
- Set your Fuel Level by pressing button A with 0.25 L increments.
- Save your Fuel Level press button B ,1 time.
Now you are ready to use the fuel gauge.
The main units screen will turn off after 120 seconds ( after last button pressed ) to consume less power. If you want to turn on the screen, just press button A once. The device only turns off the screen!! It is still working!
To turn off the device you’ll have to press button A for > 3 seconds.
Don’t forget to turn the device off after a flight, after checking your averages! ( they won’t be saved after shutdown. Only tank level will be saved. )
On the Wireless Display you can reset trip data on Screen 7 (ID screen) with button B and continue with new readings. Current Fuel level will be saved.
To see your Fuel Level press button A once to power the Remote Display.
The Remote Display will Turn off and will go into low power mode after 120 seconds. Press button A again to start the display up again.
Go trough the screens with the A button.
Problem Solving:
Before doing this you should contact me before instead!
If the Sensor starts showing inaccurate results after a while you can do a +10% to -10% adjustment on the sensor calibration value.
To adjust you have to go to the ID screen ( screen 7 ) on the main unit! and press button B.
Now you can adjust by pressing button A. The value will go from 0 to 10, then from -10 to 0 again.
You can save by pressing button B.
All other problems contact me: kixx.customs@gmail.com. And i’ll get back to you as soon as possible.
