This is what I use. Be forewarned back it off a bit when installing it mine went to 150LB on a milidon pump now maxes at 65 to 70 cold hot.
You want volume a small pump can't supply if it needs it hot under power so HV pump with right spring is just the ticket. On a HV pump in the old days I used to have 110 going out the end for 25 years don't hurt anything but using more power than needed.
