I cant get my HD7G trac hoe started
 Died on me about 4 years ago, havent done much since.  Last year new batteries filters cranks wont start have pressurized the tank and can get fuel to pump but not thru it.

Does anyone have a break down of a Bosch pump or any ideas to get this going
 I can spray wd-40 into the air box it will start

So Im pretty sure its a fuel problem

Are you sure the fuel tank valve is complet open and did you disconnect the fuel line
after the fuel filter if you have full fuel and you could use some starting fuild and you could loose the injectors line if some air in line and removed the air cleaner for make sure they are in good condition.

If it is an American Bosch PSB type pump this might help
 
 
I haven't got one yet, but have found a listing on "Allis Chalmers American Bosch Fuel Injection Pump PSB Type service manual 1966" phopocopy.  Doesn't list an Allis number in the dodger.

I send you a email and did you check the primer pump on side from injector pump and disconnect the line from the injection pump head if you have some fuel there and I have no photo for the inside pump.
