On our 830 high tin we have been loosing prime after setting for a spell. Tractor will start after bleeding the system and run"s good with no load. To get it running good we have to bleed the system and bleed it at the injectors. Is there a check valve that leaks off or where can it be getting air in the system from some place? When the system is bled we get no fuel out of the return lines either at the check valve at the front backside of pump or at pressure relief valve on top of first and sound stage filter"s. Does the pump have to come off for rebuild or I"m I missing some thing?
