i contacted spencer diesel they said if i put the seals in i should figure overhauling my engine shortly they also said i should send the pump to them for rebuild. my grandson happens to be a graduate and has a degree in diesel technology so i am pretty sure he knows what he is doing.
since...
i am trying to find the orings for a tc30 injector pump they are not perfectly round flat on inside and outside.. the one fits a groove of .747 and the other .787 they are approximately 1.5 mm thick and 2mm tall.
