A couple other things to check. How much wear is there in the linkage of the fuel pump. Also check the fiber disks and springs that hold them in place on the checkvalves. Tell me more, are parts available yet and if so where. Had a good time in england and seen some neat stuff. Busy farming here and have a funny class next week. send me a normal e-mail and we can talk more about it. l think also after this week is over it is time to stark part 2 of the Bosch PSB tech article so I will be talking to you about the tool set.
