Leak on the injection pump

[pr2501]

Thank you.
I think that i have a leak on o-ring which divide pump in two parts. But i am not 100% sure. Sanibel Jim (hello Jim) had the same problem (check some post back) I did already took all high pressure pipes down and mark the timing position. But then when i was working on input pipe i could notice that it was not tight. I have trouble now because bolt between engine block and IP is hex head bolt. But when i was looking my tools i could find home made tool, that it could be made only for this purpose and it fits perfectly. So because i do not want work for nothing specially as i have such a problem with hex head bolt i will tomorrow put pipes back and check if by any chance i have leak on input pipe. I could not see that when i was looking, but maybe because i did not had the right focus.
Tomorrow i am going on.
