sorry but forgot to list the needed data
1993 ford f150, EFI, .o engine. Camera is not here, lent it to some folks for vacation. Best I can do for now, Simply cannot believe I left out data on truck model etc. Hope this helps as the fitting that is plugged up sure looks like some sort of standard male engine side vacum fitting. Do note the hose in line is a odd hard plastic that fits over the engine side, BUT, when rubber cover on, bell shaped, the wide end fits over what seems an adapter to go from small sized hose to up one size, and it appears small end of bell fitting is supposed to fit over engine side with some sort of clamp arrangement (none there now) as is much larger then a tight fit with engine side. When I remove the rubber fabric bell cover I can plug small hose connection on line directly.
Again I apologize for a bit of rambling descriptions, but cannot find anything anywhere that describes this area of parts. I am not at all sure of function of what it plugs into, but have noted engine side plugged up or appears so. Worried if I clear it with small drill bit might not be the thing to do, it is removable but worried might break off male fitting and seems very difficult to get out...
