  • Cylinder lines? I have no idea about what you are talking about. There may be fuel injector o-rings but I’ve never heard of cylinder lines.

  • Just a guess but I suspect they have round O-rings.

  • “(C)ylinder lines”???  OK, I give up!  What are cylinder lines?  I’ve heard of cylinder liners, more commonly referred to as cylinder sleeves.  I guess you call a line cylindrical but that is just redundant…

  • What cylinders are you talking about and what kind of lines?

  • I’m going to eat dinner
