"I need some advice about the vaccuum shut off valve. I have a plastic housing of some sort on top of the fuel injector pump with two vaccuum hoses going to it, a metal thingamagig that looks like a bicycle bell with a nipple going off to the side that is NOT connected to any hose, and a short round cylinder on the back side that also has a vaccuum hose running to it. Which one is the shut off valve?"

The "short round cylinder on the back side" sounds like your shut off valve. The white plastic housing is your vacuum control valve. The "bicycle bell" is the ALDA housing
