This 1988 Porsche 924 factory service and repair manual is built around the S Coupe as Porsche configured it that year, so the fuel system procedures, clearances, and torque values inside are the ones specified for your car rather than a generic 924-series figure.

Known issues on the 1988 924. One recall is on federal record for this model year, covering the fuel system: the hose material used in the short section of high-pressure fuel line between the fuel rail and the fuel pressure regulator is subject to hardening, which can lead to fuel leaks at the hose-to-pipe fittings that could ignite on the hot exhaust system or another ignition source and start an engine compartment fire. Owners have filed 2 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures for the fuel rail and pressure regulator hose are in this manual.
Whether you're inspecting the high-pressure fuel line for hardening or working through a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 1988 924.
