Funny you should ask, I'm sitting here playing with one as we speak. It just came in today. I will install it later when my billet filter adapter comes in and the Russel lines to plumb it do as well. Looks very nice,I to will use it with the BK-209 dual by-pass mount (the kit # is BMK-15). The way is fastens to the dual pass mount is with two hollow mounting bolts that connect it to the end opposite where the line attach, the end where the relief valve is located.
It is a clean looking piece, basically a 160 cc oil accumulator with an electric controlled solenoid valve. I like the ideal much better then my old "Pre-Lubber from Sales Professionals, nothing to leak or break. I am going to order two sets of replacement O-rings, for the mounting bolts and leave them in my trucks emergency box just in case.
