I haven't been able to start the beast and thought it was the glow plugs. Turns out they are fine, but there is no fuel getting to the injectors. There is fuel leaving the box on the firewall (What is this thing? Fuel filter?) anyways it leaves this box fine, but for some reason is not getting past the piece where all the linesbranch out from? Any possible solutions you all can think of? Could there be air in the lines or something and I need to re prime? I don't know why it would have lost prime in the first place This is for a 6.2 BTW Also is this where I can tap into for an oil pressure gauge?
