Limited data — recalls on file
NHTSA has just 6 complaints on file for the 1983 Cadillac Deville — too few to judge reliability from owner reports alone — but one recall campaign applies to this year, so any used example should have its VIN checked for completed recall work.

1 NHTSA recall campaign on file. Recall repairs are free at franchised dealers.
Defect
THE FUEL FILTERS WERE PRODUCED WITH AN INCORRECT THREADED FITTING. THE INCORRECT FITTING IS SIMILIAR ENOUGH IN SIZE THAT THE FUEL FILTER MAY APPEAR TO BE CORRECTLY THREADED ONTO THE FUEL LINE.
Consequence
REPLACE THE FILTERS WITH THE CORRECT FILTERS.
Remedy
THE IMPROPER THREADING COULD CAUSE A GASOLINE LEAK WHICH MAY RESULT IN AN UNDERHOOD FIRE WHEN EXPOSED TO A SOURCE OF IGNITION.
