2L-T LJ73... Injection Pump Bleed

[Jodler]

I'm new to bleeding an injection pump, and the manuals I have don't detail this one simple point...

Where is the bleed screw?

Is it the blue circled screw, at the top of the injection pump where air might get trapped?
Or should I bled at the red circle, where the fuel input meets the pump?
Could it be green or yellow, I have no idea what those are for
Maybe purple at the base of the pump, I've seen some signals in manuals that this might be the bleed point

Also including a photo of the filter, though I'm pretty sure there's no bleed screw there though I would hand pump the air out from the filter.

Just put it all together and pump the primer till it gets stiff. Then crank engine until it starts. These are much less fussy than older inline pumps.

…worst case it’s crack slightly open all injectors lines at the head and crank until fuel from all. Then tighten and crank till she starts…

Thanks guys, will put it all back together then report back.

Purple and yellow components are important pump settings, if you have moved them around you need to return them to their original positions.

If the supply fuel line is all empty, you may want to suck up the fuel from the tank not using the tiny priming pump, but a bigger external pump or a big syringe.
You would also need to bleed the sedimenter and the fuel filter.
Good luck Ralf
