What year MJ and engine do you have? Add it to your signature.
Renix and HO are different, 2.5L I think are the same as 4.0L Renix..
Renix 5/16 line https://www.morris4x4center.com/fuel-oil-cooler-line-repair-kit-83502745.html
HO 3/8 line https://www.morris4x4center.com/fuel-oil-cooler-line-repair-kit-83504447.html
And it goes o-ring/spacer/o-ring
Just remember, there seem to be two types of 10 hole wheels, ones that have a bevel to the holes (countersunk) and the little JL indentation like the ones you're showing and ones that do not. This illustrates the differences.
