No-one here appears to know the answer, but after driving my 9-5 a couple of km extra just to find out how this type of connectors works, this has changed. Here is enough information to get you going again. The metal sleeve is permanently fixed to the rubber hose. Inside the metal sleeve is an o-ring preventing leakage and a ring of steel fingers preventing the hose from leaving the fuel rail. The 3-winged thing is just there to prevent dirt from entering the metal sleeve. The rubber hose is mounted to the fuel rail just by sliding the metal sleeved end of the hose over the metal tube on the fuel rail. This just takes seconds to do. The rubber hose is disconnected from the fuel rail by sliding the 3-winged thing away from the metal sleeve and applying a special tool over the metal tube on the fuel rail and then sliding it into the area the 3-winged thing was protecting. When the tool is pressed into the metal sleeve it will push the steel fingers away and the hose can then be pulled away. With the proper tool this just takes seconds to do.

It is basically a C-shaped "ring" with a certain size. Anything that can be pushed into the metal sleeve and push away the steel fingers should do the job. If some home-made tool is used and the tool damages the sealing inside the metal sleeve, then quite abit of expensive fuel hose has to be replaced. If you are unsure that you can release the metal fingers without damage it is better to leave the connections alone and just remove the complete fuel rail from the engine. The same type of fuel line connectors are used on other GM cars, e.g. for the fuel filter on recent Opel/Vauxhall/Saab vehicles. This means that tools may be readily available at do-it-yourself places. Good luck. -- G–ran Larsson http://www.nospam.com/saab/
