The copper lines that was on it had at least 1/4 inside for oil passage. Not really sure if I want to put these on with such small passages. All companies are selling these same two lines. Does anybody know if this is correct? And why so small of a passage? pressure over volume. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | Not really sure if I want to put these on with such small passages. The by-pass oil filter lines had a very small internal diameter. And, the size of the inlet hole is usually the limiting factor. So, yes, the internal diameter could/should be small (but does not have to be, if the inlet hole is small). | | | | | Joined: Sep 2017 Posts: 6 New Guy | | New Guy Joined: Sep 2017 Posts: 6 | thank you. I thought with such a small inlet, it would be easy to plug up. | | | | | Joined: Feb 2004 Posts: 29,804 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,804 | Regardless of the internal diameter of the lines, oil flow is controlled by a 1/16" orfice built into the filter canister standpipe. You could have a 1" diameter line, and it still wouldn't flow any more oil. As long as the hole in the flex line is at least 1/16" you're good to go.
