I was under the van today tinkering, and discovered a thin line from somewhere behind the front, passenger-side wheel to about halfway between the wheels where there's this black plastic sphere bolted to the undercarriage. The line was actually pulled out of the port where it clearly is designed to plug into the sphere, so I plugged it back in. But I could see no clear purpose for the sphere. I guess it would help to know something about the line that goes into it. Unfortunately, I'm a bit of a mechanical moron. It's a 1998 Oldsmobile Silouette. Thoughts?

This is a vacuum reservoir for the controls that use vacuum. Most notably for climate control functions. The reason for it is its used when the engine is under load(partial to wide open throttle). Under those conditions the engine will not have enough vacuum to run those controls so the reservoir is required.
You will know the reservoir has malfunctioned on some vehicles when the air from the heater will be directed to defroster. The defroster is the fail mode.

If would sound like your talking about your feul filter but I guess not it could be an air hose to help push your gas threw with the right amount of pressure?

That is your purge canister. This is where your gas fumes vent to from your tank.
