Magnafuel bypass pump pressure

Magnafuel bypass pump on stock eliminator car, 7 psi at carb, 25 psi on gauge at bypass point on pump. System looks good, pump lower than fuel cell, etc. - 8 lines, aeromotive regulator, etc. Not sure what psi should be on the pump return. System flow checks good, gallon in 25 seconds with full tank but numbers get worse as fuel level gets lower in cell and effects et? I assume five gallons has a lot more head on the pump than a lesser amount but not run into this before. Any ideas?
