The fuel pressure gauge is gonna have an electric sending unit that taps into the fuel rail where the schrader valve is right now. It's a 1/8" thread. Your gauge should have directions for install. Plus a 12v and ground for the light and a power wire for the sending unit if I remember right. The boost gauge is mechanical and will only need 12v and a ground to light up. The gauge will read off the vacuum line on the radix, just insert a "T" inline and plug in the hose from the boost gauge. You'll understand when you see it all in front of you.

Does the fuel pressure sender need anything else to tap into the schrader valve, like a T or something?
My boost guage is electric. What size T will I need for the vaccuum line? I've heard to use a 1/8 NTP to barb???

You can screw the fuel pressure sender directly into the schrader valve. You will not be able to bleed off fuel rail pressure anymore unless you unscrew the sender. You could go to a hardware store and get a 1/8" "T" and put the "T" into the rail and hook up the schrader to one and the sender to the other. Depends how creative you want to be. The boost gauge should read from the vacuum lines on the radix. they are all 1/8" so a 1/8" "T" will fit right in and hook up to the gauge. Unless an electric gauge reads from a PCM signal in which case I have no idea.
