replaced 2nd filter, still no run. Don't see any way to open up the filters from the top. Injection pump is a Bosch 30-2. On top of Bosch there is a square metal piece that looks like it holds a diaphragm. Middle of that piece has what looks like a button or a cap. Cap is loose but will not lift out of the rim it sits in. Front of pump has a cable that looks like a shut-off cable with a thumb lever. Cable stays forward when running or shut off. Only way to bleed it that I see is loosen the injectors at the engine but I expect there would be something built into the system that would bleed it. Thanks for previous answers.
 
I don't know what Bosch pump you have but THINK it's the VE pump. If engine has a turbo, the square part is the boost fuel control aneroid and the loose cap is covering the fuel cut back-no boost fuel setting, normal for that cap to wiggle around. Pump is self bleeding, just need to loosen lines at injectors. A picture would help.

sorry, can't do pics.
 
Dieseltech; I have a 10006 Deutz with a bosch rotary pump on it. It has been setting for over a year. Do those pumps go bad from sitting? & will it run away if started?

That Bosch rotary pump is hydraulic governed, I've never seen one run away like mechanical governed pumps can. If it runs, count yourself lucky, if not good luck finding parts...

So how does a hydraulic governor work? I can understand one with flyweights.

When I was at the Bosch service school YEARS ago on the Bosch AR, BR, and CR pumps for a week, everyone could tell you how it worked then. The instructor said He thought the guy that designed it was in a Rubber room somewhere wearing an I love me jacket, then we all forgot how it works.....
 
I just looked at the parts list, it's the Bosch VE pump.
plenty of fuel coming out the 2nd filter to injection VE pump. Appeared to be a slightly wet dust on pump & all around. Ignition on & wiggled the hose coming out of the back of the pump from a short curved metal pipe. Back of the hose clamp holding it on, the rubber line had tiny splits in it where very small fuel leaks were. Cut the bad end off & re-clamped it for now. No start. Loosen nut at injectors, no fuel til I cranked engine. Guessing it will take someone cranking while another tightens the nuts? I'm alone. Leak might be a return line? I was wondering why it would lose its prime after 25 years of staying prime; leak was all I could think of. Would the leak I cut out cause it to lose prime?
