Or I use two rubberised 'P' clips from the horizontal frame tube just below the reg/rec. But my cooler is from a VW.
Bypass spring goes under the filter hexagon stud, there is a raised cast portion on the crankcase for the spring to react against when tightening the filter stud.
Depending on the spring you may need to trim it to locate against its arrester.
