As I see it, I shouldn't be able to pump through the injection pump with the venting screws closed, but I'm talking about when they are open. Pressure still builds up when they are open, and only very small amounts of fuel comes out when bleeding. That, combined with the fact that the lift pump stops "gripping" after a couple of pumps (if I wait a while, pressure is reduced enough to let me do another pump) indicates to me that somewhere the fuel has a hard time getting through. Since loosening the incoming pipe to the injector pump releases this pressure, it's now narrowed down to either being the filter screen (hopefully) mounted on the inlet to the injection pump, or somewhere inside the injection pump.
Unfortunately the weather gods have decided to make it rain here today, so I'm not going to check this until tomorrow at the earliest (depending on the weather).
