Belarus 250as injection pump question

[prolinews]

I'm having issues with my tractor. It sat for a year cranks idles then dies. I drained the tank checked ever line filter etc. I have narrowed it down to the injection pump or booster pump. When it's idling I can pump the booster pump and it throttles up like normal as long as I'm vigorously pumping the hand pump. I am not sure if that's a sign the booster is bad or the injection pump? I've seen the booster pumps on the net for sale and have only seen one injection pump for sale and it ships from Belarus. I'm not sure what I need?

Any ideas?

have you checked the sediment bowl, and changed the fuel filter as well? maybe add some fuel treatment if sitting for a long time. sounds like a restriction from moisture or sediment. fuel quality has to be good esp if sitting for as long as you describe....try purging all fuel lines to injector pump if possible best

Drained the entire system blew out every line went through the filters. With the way it runs when I pump the hand pump makes me think the transfer pump, I ordered a new one today. I sure hope it's not the injection pump.

Of course the pump shows up, ten minutes before I leave on a 3 day trip. ....
