Known issues on the 1987 Skylark. The 1987 Skylark carries 1 recall on the federal record, and it concerns fuel lines near the transmission. On certain 1987 Skylark vehicles with the five-speed transaxle, 22,300 in total, the fuel feed or return hose at the engine could rub against the shift lever until it wore through, letting fuel into the engine compartment and risking an underhood fire. Dealers replaced the feed and return hose and pipe assemblies. The fuel system and transaxle both sit within the manual's procedures, specifications, torque values and diagnostics.
