My FE/MF35 (not sure which it is!) with 23C has a problem at the moment in that I'm constantly getting air in the injector pump, which will cause the tractor to stall.
At first I thought it was just due to bouncing over some rough ground, shaking up the fuel and sucking through some air. But now its happening very often on flat ground with a full tank of fuel. It appears most when I'm working the tractor - not so much at low rpm/load. I suspect because the auto air bleed off system can't bleed it off quick enough? At the moment I'm trying to mow 5 acres with a 4 disc mower, its cutting out and I'm having to bleed the pump about every 2nd lap around the paddock.
There is no sign of air in the rest of the fuel system, cracking the top bleed screw on the pump, then bleeding the injectors gets it going every time. I cant see any fuel leaks, although the small cyindrical shaped device attached to the bottom of the pump does appear a bit weepy and the cork gasket between this and the pump is a bit swollen.
Where is this air getting in? Could it be a dodgy pump gasket somewhere like the one I mentioned?
