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. 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.
