What is this?
I'm an F-series guy, but my son had some troubles with his 93 B2600. I had to replace a hose on his truck that went uderneath the intake. To get at it, I had to temp. move an assembly that was mounted on the vaccuum canister. There are 2 electric powered vac control modules. Well, when I went to move them, I had to unhook a vac line from the canister.... and ofcourse I broke 
the brittle plastic on the control module where the vac line hooked on.
This module is Mazda part # 18-740E.
What is the purpose if this module? Currently the vac lines are bypassing it and everything seems fine and my son says the truck starts better.
Any info would be appreciated!
Thanks

I found some info on the net. The part is a "Purge Control Solenoid Valve". After looking again, it wasn't the vacuum canister - it was the carbon canister that it hooked to. The dealer is the only place I found and the part new ($70)... so I went to the junkyard and got it for $2. I don't think it really does much - the valve is open anytime the truck's engine is at operating temp so I probably could have bypassed it with little or no difference.
The truck is all put back together and running better than before (found some vac leaks!)
Thanks Ken and Tex.
