The FI setup will have to wait until next year for $$ reasons. I'm putting a bg220hr pump in my bb'71. The pump uses a -8 feed line to the carb, and a -10 return to the tank. In the Barry Grant plumbing diagram, it shows the reg. mounted right on the fuel rail at the carb, then going all the way back to the tank. http://www.barrygrant.com/bgfuel/default.aspx?page=85 What i'm thinking is why waste all that -10 line running from the carb to the tank, when I could have the regulator mounted at the rear near the pump and have it dump the fuel right back into the tank with only a few feet of line rather than another 15 ft. of fuel line. Most major auto manufacturers do it like this now. I've been a BMW technician for years and they've been doing this on all models from a base 325 all the way to M5's. It just seems inefficient to run the line there and back twice. It would make for a cleaner install and save at least 100 bucks on line.
