Known issues on the 1988 Seville. One recall is on federal record for this model year, covering the gasoline fuel system: certain replacement fuel filters were fitted with a connector not built to specification, so the O-ring may fail to seat correctly on the fuel line, creating an inadequate seal at the connection. That can lead to a fuel leak, and in the presence of an ignition source, a fire. Owners have filed 26 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 OEM procedure and the correct specification for your specific 1988 Seville.
