Don't worry about that jet. It can happen when bleeding a brake system in my experience. My truck did the same thing and I've had it happen on other projects so I know exactly what you are referring to. Have you tried gravity bleeding again? Crack the lines just before the prop valve to see if you can get fluid to that point. Next see if you can get fluid to the tee on the front crossmember for the front brakes and the union for the rear brakes. If you can get fluid to those spots you can bleed the system as you normally would.
