Important Notice
********** Must Read **********
If you think it is not important to read this manual, you're wrong! This manual
contains important information that may affect the safety of your aircraft.
Read the Warranty / Agreement. There is information in the Warranty / Agreement that may alter
your decision to install this product. If you do not accept the terms of the Warranty / Agreement, do not
install this product. This product may be returned for a refund. Contact Electronics International inc. for

The fuel remaining displayed by the FP-5 is not a measurement of the fuel in the tanks. It is an
amount calculated from the starting fuel level you programmed into the FP-5, minus the fuel used while the
engine was running. When properly calibrated, the FP-5 can accurately measure the fuel used. It is im-
perative the pilot verify the calibration of the FP-5 over many tanks of fuel before using the "REM"
and/or "USED" Modes as an indication of the fuel in the tanks or fuel used. Even after verifying the
calibration of the FP-5 it should never be used as the primary indicator of fuel quantity in the tanks.
It is important the pilot visually check/measure the fuel quantity for each tank before takeoff and
cross-check these readings against the Fuel Level Gauges and the FP-5. The FP-5 reminds you to do
this by blinking the “REM” LED and displaying the current fuel remaining in the tanks each time the
aircraft power is turned on. Also, it is important the pilot use preflight and flight planning techniques,
in accordance with the FAR's, which will help insure the proper amount of fuel for the intended
flight is on board the aircraft before takeoff.
While in flight the FP-5 readings should only be used to crosscheck fuel level gauges, calculations
of the fuel onboard from flow rates specified in the specification for your aircraft and calculations of
the fuel onboard from flow rates that you measured from previous flights. The use of the FP-5 does
not eliminate or reduce the necessity for the pilot to use good flight planning, preflight and in-flight
techniques for managing fuel. If you are not familiar with these techniques, contact the FAA to
acquire proper training.
Before leaning your engine you must verify your horsepower is correct with engine operation
charts from the engine and/or aircraft manufacturer to insure you do not cause detonation and
engine damage.
It is possible for any instrument to fail thereby displaying inaccurate high, low or jumpy readings.
Therefore, you must be able to recognize an instrument failure and you must be proficient in operating your
aircraft safely in spite of an instrument failure. If you do not have this knowledge, contact the FAA or a
local flight instructor for training. Also, the ability for this product to detect a problem is directly related to
the pilots ability to program proper limits and the pilots interpretation and observation skills.
The pilot must understand the operation of this product before flying the aircraft. Do not allow anyone
to operate the aircraft that does not know the operation of this product. A copy of this manual must be kept
in the aircraft at all times.
