INSTALLATION INSTRUCTIONS
ELITE SERIES
FULL SWEEP ELECTRIC FUEL LEVEL GAUGE
2650-1443-00
CAUTION!
As a safety precaution, the +12V terminal of
this product should be fused before connecting
to the 12V ignition switch. We recommend
using a 1 Amp, 3AG fast-acting type cartridge
fuse (Littlefuse
®
# 312 001 or an equivalent).
Installation - Fuel Level
1. Check that you have all parts required for installation, and the
engine is cool.
2. Disconnect the negative (-) battery cable.
3. Gauge mounts in a 2
5
⁄8" hole for 2
5
⁄8" gauges, and a 2
1
⁄16" hole
for 2
1
⁄16" gauges. Use supplied brackets and nuts to secure
gauge to dash.
4. Drill 1” diameter hole where wires pass through sheet metal
(such as firewall) and install rubber grommet provided.
(Grommet will require slit.)
5. Connect the white wire to dash lighting or switchable 12v light source,
the red wire to switched +12V source and the black wire to ground.
(see diagram for details)
6. Connect purple wire to fuel level sender, making sure that the sender
is grounded.
7. Reconnect negative (-) battery cable.

NOTE: When the ignition is off the pointer may not always
rest at zero.
1. The gauge ships pre-programmed to read GM 0-90 ohm senders.
2. If any other sender type is required press and hold the “A” button and
apply power to the gauge. Keep holding the “A” button until the dial
illuminates blue (about 15 seconds).
3. Release the “A” button, the dial will move to the 1/8 tank mark
indicating the current selected sender.
4. Press the “A” button to move the pointer down to the next 1/8 tank mark
or press the “B” button to move up to the next 1/8 tank mark stopping
at the desired sender type (see chart below). Holding the “A” or “B”
button will allow the pointer to sweep in the selected direction stopping
briefly at each 1/8 tank mark.
5. When the desired selection is indicated remove power from the gauge
to store the new sender type by turning off ignition switch.
6. Re-apply power to the gauge, and confirm that it reads the proper
fuel level. If the proper fuel level is not read, return to step 3 and
recalibrate. If the proper fuel level is still not indicated, perform Custom
Sender Calibration. If there is still no proper function, the sender circuit
may need diagnosis. Please call our technical support for assistance.
The fuel level gauge can be custom calibrated to accurately display the
output from any fuel level sender with an output between 0 and 270 ohms.
1. Make sure the fuel level sender is connected to the gauge and that the
fuel tank is empty, or nearly empty, before proceeding.
2. Press and hold the “A” button and apply power to the gauge. Keep
holding the “A” button until the dial illuminates blue (about 15 seconds).
3. Release the “A” button, the dial will move to the 1/8 tank mark
indicating the current selected sender (see chart below).
4. Press and hold the “B” button until the pointer sweeps to the 7/8 tank
mark. This will select the custom sender.
5. Remove power from the gauge to enter custom calibration mode.
6. Re-apply power to the gauge, the pointer will move to a position just
below the empty mark, indicating that the empty calibration point can
be entered.
7. With an empty or nearly empty tank, capture the empty calibration
point by momentarily (less than one second) pushing the “A” button.
After approximately 1 second, the pointer will move to just above the
full mark.
8. Fill the tank and momentarily (less than one second) press “B” button
to capture the full calibration point. After approximately one second,
the gauge will reset, and begin reading fuel level per the custom
calibration.
9. Confirm that the gauge reads the proper fuel level.
10. If proper fuel level is not read, return to step 2 and recalibrate.
Custom Sender Calibration
If no sender is connected, the pointer will move to the empty position indicating an error. Approximately 4 seconds after the sender is connected,
the pointer will move to the indicated fuel level and will resume normal operation.
