I was getting ready to hook my injector rails up last night and one O-ring on the return line tore. Does anybody know what size (I measured the grove @ 11/32nd's) for sure these should be, and if they need to be a special material?
OK, I got a pack of assorted fuel safe O-rings in the "Help" section @ Oreillies. I was able to fish one out that was pretty dang close, the thickness of it was a little small (compared to the other factory O-ring that has been smashed inside the rails for 20 years), but it fit nice and tight.
