Case 930 fuel system help

Hello, thanks for taking the time to review my issue and help out!

I acquired a 63' 930 with an acreage I recently purchased and I am having troubles with bleeding the fuel system. I have read over the related posts but I cant pinpoint a solution.

Heres whats going on. I suspected that I got air into the fuel system when the tractor didnt start after sitting for some time and proceeded with checking and replacing the filters. Now, I am attempting to bleed the system like I have read all over but I am not getting any fuel into the secondary filter. Primary filter fills up and bleeds perfectly (With the use of a shopvac blowing in the tank to pressurize as my hand primer is no good). As I said no fuel is getting to the secondary filter at all.

Also, I tried to remove the plunger between the filters it doesnt seem to help, although I can hear lots of air flow going through that tee where the plunger sits, but again no fuel coming through.

Thanks again!

Did you replace the third filter up by the
radiator? Not that that should stop the
second filter from bleeding, but many new
case owners dont know its there, and tho
rare, they do plug. If the tractor sat for
a long time make sure the rack is free so
you dont get a run away. The rack is under
the round plug with flats for a wrench on
the end on the front of the pump. Pull the
cap off and make sure it moves freely when
the throttle moves.

As far as bleeding the second filter it can
take a while, but if fuel is flowing
through the first filter it should get to
the second. Is air coming out of the
bleeder hole?
 
Which version of 930 do you have? Is the fuel tank behind the seat or in front of the steering wheel? If it is up front having the tank full will help with priming. I would recommend fixing or replacing the primer pump. It will make priming much easier. My 930 comfort king (fuel tank behind the seat) has an electric fuel pump down by the tank that is wired into the ignition switch. It was added later but works great for priming the system. As it was stated it does take a long time to get fuel all the way to the injection pump when priming. If you hop down to the Case/David Brown forum below you will get more answers. Good luck.

Thanks for the response, I didn't change the third filter as the secondary looked pretty good. There is air coming out the bleed hole yes. I suppose I could try longer to see if that helps.

Thanks again
 
Ya mine is the 930 comfort king with the tank behind the seat, electric pump sounds like a good idea I think I'll add that as soon as I can!

Thanks
 
I gave it a try today again, I made a bit of progress but I am still having trouble with it. So the first filter still has a good clear
fuel stream, then I closed it, after a really long time (probably close to an hour) fuel started to come out of the secondary bleed, as
well as the plunger housing at the top. The fuel coming out of the bleed hole is clear until I put the screw in, then it starts to starts
spitting air at the final filter and plunger housing and doesn't change no matter how long I leave it. I then removed the bleed screw in
the secondary again until the flow clears up and then tried to close the plunger housing first, it then just spits air out of the bleed
hole and next to no fuel no matter how long I leave the pushing fuel through. Is my process wrong or am I missing something? There is alot
of snow on my property and more coming down right now, I really need this thing to fire up. I should clarify from yesterday day, when I
said the tractor was sitting for a while, it was only a month not long enough to have caused an issue anywhere I dont think. We had nearly
2 weeks straight of about -40c during that month.
