can we talk vac pump?

i put an aerospace on my 440 and today at the mopar nats first pass, the canister actually overflowed with oil and it was blowing out the breather as well. obviously something was done wrong and it was my bad, i'm sure. :) i think i know where i went wrong but does anyone out there ever had a learning experience with one of these things. in the pic there is the fitting coming out of the valve cover. is placement wrong with the fitting and of course there is no baffle? ok,,,,,,,let me have it,,,,,,i can take it. thanks yall
