vaccum line under radiator that runs to charcoal canister

[ultimatesho]

in the process of dropping the oil pan to check my RB's i fianlly got around to replacing this line (from the T to the canister)

i took out the T just to make sure there was no cracks or nothing and i found that the right hand side (side that runs to the passenger side into the plastic hardline) was blocked off......looked like someone had super glued a little brass stopped in place.....so curious as i am i finally got the pace to pop out and after cleaning the glue or whatever off of it i noticed there a pin point hole dead center of it

so my question is this is the little stopper suppose to be in there for some reason????? or are all 3 ends suppose to b free flowing?????......and if it is suppose to be in there is it suppose to b a complete block or just have that pin point hole????

:thankyou: in advance

that line allows engine vacuum to continously suck fumes from the tank. the pin hole is there to limit the amount of vacuum. are you sure the "stopper" wasn't a chunk of gunk?

no this was a actual brass stopper on the right hand side of the T......the stopper did have the pin hole in it though......but i had to clean what looked like old super glue off of it
