I got some stuff delivered. The coil connector didn't fit, it was for a much smaller VW 4 pin. So I sent it back.
Mike Pickett graciously mailed me an extra he had, that's on the way. Thank you, Mike! The coil is a Bosch and looks exactly like Mike's.
I saved some money on IAT and CHT sensors, I got them both from Ballenger Motorsports for $53 shipped, way cheaper than CB. Plus, they came with pigtails too, so I saved about $60 on sensors and connectors. They are both 1/8" pipe thread, so very small. I got my injectors too, and 4 connectors. I'll post a pic when I install them.
I did some work on the fuel system. I took the fuel rails, injectors, air filter tops and velocity stacks off the throttle bodies. Cleaned up the whole she-bang.
The throttle bodies measure 48mm on the bottom, and 49.5mm on top. The velocity stacks measure 46mm at the bottom. I'm seriously considering making aluminum shims to make them 44 or 45mm throttle bodies, albeit with 48mm throttle plates. If the smallest point is 46mm, there is no need for a bigger hole/passage IMHO. The only thing a larger passage does is lose velocity. I may see how it runs first, this might be a non-issue with injection vs. carbs. The injectors are below the throttle plates. I know that the top of my manifolds are bigger than the bottom of my 44mm carbs, but I didn't measure them.
I decided to use a Subaru fuel filter. All the connections on the pressure side are hose barb(8mm or 5/16") under the tank, so I'll use some Continental EFI hose and those fancy EFI clamps bandied about in that other thread(Jimmy's). The regulator is ready to go and the fuel pump works. Everything on the pressure side in the engine bay and on the entire return side is 6AN. I'm going to drill a hole in the top of the fuel tank and install a 6AN bulkhead fitting. There will be a metal tube inside the tank that returns fuel to the bottom of the tank: no bubbles. I need to run another 5/16" metal hard line down the center. It's 58" long so a 5 footer is perfect. As I found out before, 5/16" fuel line is good for 350hp.
