For anyone running the Bosch 160lb/hr or 210lb/hr injectors, did you have to change out the O-rings on them, and if so, which ones did you use?
I've got a set and I was comparing them to the rail and some old injectors. On my cheap calipers the O-rings are the same dimensions on the old injectors and the new Bosch ones- roughly 14.2mm OD, 3mm cross section. (Despite the Bosch official drawings calling out 13mm OD)
But when test fitting them in the rail they feel a little different. They both are very snug getting them in, then a little looser as you sit them deeper. But the Bosch ones take just a little less force. Not by a lot, but I can notice it. I don't know if I need bigger O-rings for them or not.
