Not necessarily a rough idle but would fluctuate ever so often. Runs fine and haven’t noticed anything else. It does have a slight fuel drip from the very back of the pump.

    That part is the fuel pulsation damper. It steadies the flow through the throttle. Usually they never go bad and are reused time and time again, pump rebuild after rebuild. If that is indeed the leak It has an big o-ring in between it’s two halves and a small 0-ring were it mounts to the gear pump.
