Lister Petter LPW3 Engine Not Starting

I have an old LPW3 Alpha series Marine Diesel engine that has all fuel lines in working order. The diaphragm is sucking and pumping fuel through the fuel filter, but is getting blocked around the starter (near the oil filter). It seems like this is the last point where things are mucking up.



I wanted to know the name of the piece in the image, as well as if anyone has an image for said piece. What would common problems be preventing fuel from getting from point A to B?


(In the image, the arrow represents the lever that allows fuel injection. The circled part is the name of what I'm looking for + image/diagram, and where I suspect fuel isn't being delivered to the cylinders)

Re: Lister Petter LPW3 Engine Not Starting

Here's a parts catalogue pic of the gear case and governor.
I have no ideas about the fuel line / starter motor issue but all of the injector pumps bleed screws and HP injector lines are hidden behind the heat exchanger. I had an STW3 ( similar construction) in a previous boat and it was a difficult engine to bleed after air got into those pumps. Click image for larger version
