a-904. Still leaking after rebuild! :(

Well, it leaked overnight so it definitely leaks while not running. It drips while idling in neutral, but I don't know if it's actively leaking then, or if that's residual from just leaking in general. I would think that if it leaks while not running, it would also leak while running, right? (I don't think it's an over-full issue leaking when the pump drains or whatnot because in the morning, the fluid is low)
