Yep, saginaw. And with adaptors you will still have the restriction of the fittings. It's not hard to get some weld bungs and cut the fittings off the rail and bottom or the regulator. Just another option.

The Saginaw adaptors have been posted somewhere. Might turn up in a search.

Thanks for all the replies.You are right on the restriction of the saginaw fittings.So what the procedure or parts needed to weld the fittings on?How much do you cut off the fuel press reg?Will the heat from welding screw up the FPR?What fittings would I need?Thanks Tony

On the feed I cut off the fitting behinf the hex right where it is brazed on. I then welded a male -10 steel fitting.
I cut the regulator off similiar to the feed and welded a male -6 aluminum fitting to it. It did not appear to warp it since I still get the same 1:1 fuel pressure increase, but it is possible. Find someone that tigs aluminum well. I don't know if I have to tell you to dissasemble it first, but yeah.... dissasemble it first (assuming that you have a billet style AFPR).
