I have concerns that there may be a fuel pump or restriction issue that I have recently noticed. The tractor has 140 hours now.
The glass filter bowl empties to 1/2 level when the tractor is started and stays at 1/2 to 1/3 level until the engine is stopped when it then fills to the top.
My concern is that with this screen filter, could it be sucking air to the injector pump which would be damaging to the injectors. I have replaced the glass bowl screen element and both spin on fuel cartridges with no change and even blown compressed air into the tank in case there may be a restriction clogging up the tank inlet.
Is this normal for a 75A to see this on the pre-filter screen or should it be full all the time?
