How much air do you anticipate the pump is going to deliver into the system? If it would not overwhelm the filter, is there a possibility the pump could be plumbed before the filter rather than after. If it requires a pressure feed, am thinking with the restrictions, after the filter might not have enough flow.

If it would not flow thru the pump unrestricted enough to lower pressure significantly, what about taking the supply from the unused opening at the rear of right head to the pump and then teeing into the filter return. I don't remember it dropping into the chain area as I thought there was only the one opening via the cam plate, but haven't looked recently. Even if it does, don't think that would cause an issue.
