I used the search button first, no dice. I'm looking to replace the stock cooler lines with new high pressure hydraulic lines. I did read that a 5/8 18 would work for the fittings, but how big is the I.D of the line? Any help or direction is much appreciated.

 

look thru this thread. It has all the info you need. I basically ordered atomics parts list and it was dead on.

 

What thread exactly? I think i missed the link. Sorry
