Known issues on the 1989 DeVille. One recall is on federal record for this model year, covering the fuel system: certain replacement FRAM fuel filters sold for use on these vehicles had a connector that was not manufactured to Honeywell's specification, so the O-ring may not seat correctly on the fuel line, which can create an inadequate seal at the connection, potentially leading to a fuel leak, and in the presence of an ignition source, a fire could occur. Owners have filed 58 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind the fuel system are here.
Whether you're inspecting the fuel filter connection or working through a routine service interval, it keeps you on the correct OEM specification for your specific 1989 DeVille.
