line lock not releasing?

ill bench test this one tomorrow, after i replace it
what exactly am i looking for?

obviously when it is closed when it should be open, thats pretty obvious, but could it be not opening enough?

i called in last night to Jegs, they are sending a new one out today, which should be here tomorrow

other then thinking about it, im gonna let it be for today (as in, not getting my hands dirty)

With the lock disconnected or off, you should be able to blow through it both directions with near zero resistance.
