Page 3: Introduction
The FF-2 unit can connect to one or two fuel flow senders, one or two fuel level senders or both. Full functionality is available with both senders or only with a fuel flow sender using calculated fuel levels based on fuel usage. -

MGL Avionics Fuel management FF-2 & FF-4 Install & User’s manual Setting up the FF-2 / FF-4 Press the Menu key to enter the menu. You can move forward and backwards in the menu by using the keys. To change or select a menu item, move the highlight to the desired item and then press the Menu key. -
Page 7: Speed
MGL Avionics Fuel management FF-2 & FF-4 Install & User’s manual Speed Enter your aircrafts cruising speed. This value will be used to calculate the fuel range, i.e. how far you can fly with remaining fuel at zero wind speed. For this calculation, your current remaining fuel, your current fuel flow and the speed entered here are taken into account. -
Page 8: Setup
The K-Factor is the number of pulses generated by the fuel flow sender for one liter of fuel. The dual range fuel flow sender supplied by MGL Avionics has a K-Factor of 7000 in the low flow mode (jet installed) and 1330 for the high flow mode (no jet installed). -
Page 9: Alarm
MGL Avionics Fuel management FF-2 & FF-4 Install & User’s manual • This example would mean that our fuel flow sender is under reading by four liters as it has not measured the correct quantity of fuel. • Now start adjusting the K-Factor so your tank level changes from 28 liters to 24 liters. - Page 10 MGL Avionics Fuel management FF-2 & FF-4 Install & User’s manual of cheap level senders can prove troublesome, as the lever arms tend to be sticky. This prevents the floats from floating on the surface of the fuel at all times. As a consequence, this will lead to incorrect fuel level indication.

Page 11: Notes On Slope Error
Notes on Slope error Sender value is a value determined by the FF-2 or FF-4. It is used to calculate e.g. fuel level, fuel endurance estimate and current range estimate. The fuel tank setup sender value can either increase in value as fuel is added on decrease in value if fuel is added. -
Page 12: Installation Ff -2 & Ff-4
Fuel flow sender Please observe the installation notes supplied with the fuel flow sender. Should you install a different fuel flow sender to that supplied by MGL Avionics, ensure that you enter the K-factor relevant for your sender. Some senders require a pull-up resistor to the 12V supply line. We find most installations of these senders require a 4K7 pull-up resistor. -
Page 13: Connecting To An Injector
MGL Avionics Fuel management FF-2 & FF-4 Install & User’s manual Connecting to an injector This image shows the connection of one injector (controlled on ground side) and one fuel level sender. • When injector is controlled through ground, select “Injector High” in Setup. -
Page 14: Level Sender
Install & User’s manual Level Sender If required the FF-2 or FF-4 can interface to a standard automotive fuel level sender(s) as indicated. Most of these senders are resistive types. The level input terminal has an internal 1K resistor pull-up to 5V. -

Page 16: Warranty
Install & User’s manual Warranty MGL avionics warrants their products for a period of one year from date of purchase against faulty workmanship. Warranty is limited to the replacement of faulty components and includes the cost of labor. Shipping costs are for the account of the purchaser.
