'92 Park Avenue Ultra

Im looking for a diagram of the supercharger and or the engine. I tried Haynes manuals but couldnt find anything about the 3.8 supercharged.

The reason im looking is a hose that feeds coolant to the supercharger
(im assuming only because it is right below it) has a plastic fitting on the end of it that cracked clean in half and dumped all the coolant.
Ill take a picture of it tommorow in case i didnt describe it well enough.

Any help would be appreciated.

Replace the nipple with the new design metal one!
