Fuel gauge
Problem
Possible cause
Action
Fuel gauge shows empty
at all fuel levels of fill
Loose or dirty wiring connections or
short to ground wiring

assembly. Repair, clean or righten as
needed.
Leaking sender float
Replace sender
Missing sender float
Install float. Make sure float is secured on
sender arm.
Short circuit in sender assembly
Test for correct resistance values and
replace as needed.
Sender assembly arm movement
obstruted
Inspect fuel tank and sender for
cause.Correct or replace faulty component.
Fuel gauge will not read
full when tank is full
Wrong sender installed
Check part number. If incorrect, install
correct part
Sender arm movement obstructed
(float rod bent)
Inspect fuel tank and sender for cause.
Correct or replace faulty component.
Leaking float
Install new sender
Sender or gauge calibration
Test correct resistance value and replace
component as needed.
Fuel tank not filling to rated capacity
Check fuel tank fill vent for kinks or
obstructions.
Correct as required and fill tank to verify
proper capacity.
Fuel gauge shows full at
all fuel levels
Loose or dirty wiring connections or
open circuit in wiring
Check wiring, connections and sender
terminals. Repair or clean if required.
Open circuit in sendng unit
Test for correct resistance valves and
replace if required.
Sender arm movement obstructed
Inspect fuel tank and sender for cause.
Gently bend float arm away from
obstruction or replace component.
Fuel gauge reads
incorrectly, but all fuel
system components are
running properly.
Fuel tank damage
Fuel sender mounting angle may have
changed or the sender unit may be
