Contact a FASS dealer about upgrading to the ADJ pump head. Have them call me. I would ask that it be sent in to keep your wnty in good standing.
Its very odd that the pump is dropping that low.....about the only other thing i can see is debris in the regulator ball seat.
Either way, have your dealer call me...
