Viss1,
I used an AN (aircraft type) fitting tee. I believe at least one other person has done this and used normal hardware store plumbing fittings. I went with braided line from block to tee. Ordered the fittings, etc. from
www.anplumbing.com They have a large selection of fittings and hose. I used #4 Hose, a 45deg hose end @ block, straight hose end @ tee. The tee is their pn: 991702 It has 1/4"NPT female threads on all three openings.
Hope this helps.
