I went ahead and got this one too GRI-1-25222-X. but I did not get it from Summit. I got it off ebay like $168 shipped. Seems to fit fine without the cap...I need to get a cap for it. I also got the hose B71011 and it is too big for the WP. I guess you can cut off a piece of old hose and leave it on and push the new hose over it. Made some Z shaped brackets to bolt into stock loc. from some metal I found at home depot and bent it in the vise with a hammer....they were over in the lumber section for joints like $1.35 apiece. Gonna try and use a 14" fan and shroud I had off an old dual radiator setup I had gotten from a Hyundai. Should be fine. No pics yet.
