MCW462 pressure drop vs. flow

I need some help, and would offer the below graph

here is a plot showing the head loss of the MCW462 with the "stock" 3/8in. 90^ push-on fittings, and with 1/4in. NPT x 1/2in. barbed




in exchange I'm asking for the installed MCW462 spring height:
could someone please measure the installed (compressed) spring height on a stock setup of a Swiftech MCW462 ?
(all 4 to be sure they're equal ?)
and post it (or e-mail me - [email protected] )

Thanks

be cool
