Known issues on the 1988 DeVille. One recall is on federal record for this model year, covering the gasoline fuel system: a replacement fuel filter fitted to these vehicles was built with a connector that did not meet the original specification, so the O-ring may not seat correctly on the fuel line, creating an inadequate seal at the connection that can lead to a fuel leak and, near an ignition source, a fire. Owners have filed 37 complaints for the year. The factory diagnostic and repair procedures behind the fuel system are here.
Whether you're tracing a fuel line for leaks or working through a routine service interval, it keeps you on the OEM specification for your specific 1988 DeVille.
