For fuel lines and fittings, all 1991-94 Saturn vehicles utilized a spring-lock coupler fitting at the engine side of the fuel filter and a quick-connect fitting for the remaining fuel line connections. However, all 1995-98 Saturn vehicles utilize quick-connect fittings throughout the entire fuel line system.
The spring-lock coupler fitting is an integral part of the fuel filter assembly that requires the use of a special tool, usually provided with the filter replacement kit.
The quick-connect fitting consists of a male and female plastic connection. These two connectors can be snapped into place (or unsnapped) without the use of any special tools.
