You should only be running the main pump and never both at once. The aux pump is just that and should be used when the main is out of service. IMPORTANT .. Headhunter pump and Micropher toilet owners should never have the pumps turned on when hooked to City water as you are adding the city water pressure to the 65lbs the Headhunter pushes and that is often too much pressure for the valves in the toilet and can be a costly headache. Clean your "Redhat valve" diaphragm and put back the same way you found the membrane and turn your pump OFF during "Auto-Fill" as you don't need it to run throughout the fill process. The Shurflo Extreme series can push the same 65lbs that the Headhunter does.
