I found the same model that Kelly found; it looked like it had two barbed fittings and a MAP port. That one it would do fine, but I'd like threaded ends if I can find them. I gave up on the speed shops & took a shot at (ugh) Autozone. Much better info & hundreds of selections. Just about all their product is made by GP-Sorensen. The AZ site has some info; model application is available at the GP-S site: http://www.gpsbrand.com/web_app/gps_bgbulk.aspx The models that I flagged for further inspection are (all start with 800-): 800-408 -284 -180 -218 -411 -183 None of the info I could find gave thread sizes. Pressures varied from mid 30s to mid 60's. None had adjustable pressure. I'm hoping I can fab a block to accept both pump outputs, the regulator, and a tap for a pressure gauge. Should be fairly simple using a drill press & a few taps; also have access to a neighbor's lathe & mill if needed.

What have y'all been using for a regulator? The online speed shops seem to have very limited info on their regulators (MAP sensing, in/out connectors, even regulation pressure).

OEM regulators are cheap ($23-$50) but all I've seen would require a machined adapter block. The in-line types that I've found that are well documented & should work, are fairly expensive ($120+). My intent is to insert the regulator immediately after the high pressure pumps, on the cockpit side of the firewall, common practice on new cars & I think that's what Tracy did on the RV-8. Some of the inline regulators don't seem to have MAP sensing; is anyone using a regulator w/o MAP sensing?

Thanks,
