JD 2150 fuel prime

[BRWEEKS]

Having issues getting fuel through the injector pump to the injectors.
Good pressure to it.[inlet]. Just can’t get it to the injectors. Return line and ball valve are all fine. No crud and some fuel in them.
Any ideas or tricks. Is there one of the bleed bolts on the pump that can be opened that will help. Opened one of the fuel lines on the pump with no fuel there. Seems likely it could be the injector pump. Just had one rebuilt on an 820. A $2500 date. Tractor has 1565 hours. Little or no use since 2021. But it was OUT of fuel and I’d say was tried to start dry. Much appreciated.

Maybe TBN member thepumpguy will chime in here and can give you some help. He is good.
Provide some pump names and maybe some pics of what you have run across or run into in the meantime.

Are you into repairing 820's ??

Thank you. Perhaps the pump guy can provide some tricks to prime the inj pump. Really never had issues doing so in the past. However, never really had to prime a tractor that was completely ‘dry’.

The 820 is a 3 cyl my grandfather bought new. I keep it maintained. Just had the roosa master rebuilt and installed new injectors. Runs mint now. Hoping I don’t have to do the same with this 2150. What are the chances.

It could be something as simple as a stuck metering valve.. Google it and come back or email me directly.

Well, it’s not the metering valve. Pried if off yesterday and all moves fine and clean as a whistle. Roosa Master is coming off. Like the 820 earlier this summer. I’ll have the HP pump rebuilt and injectors replaced. So, here’s a crazy question. Can the pump be “turned up” just a bit and if so, injectors upgraded as well?

Yes, it’s not uncommon to ask your rebuilder to turn it up 10%..
I’ve never “upgraded” injectors so I can’t comment on that.. but I would think that to 10% would suffice..
