the bolt, not required to replace, just use new threadlock after cleaning..
the nuts, replace, they are self locking deformable (the new ones anyway)
the nuts that came off my old pump were different than the new ones, and the new ones seem to be a lot more secure.
what you are supposed to replace that nobody ever does is the 3 o-rings that go on the oil tubes to the pumo.
