Default Fuel and Boost guage install - HELP!

Ok, got the guages, and the A-pillar mount, now:

Fuel Guage (Electric) - WTF is a schrader valve and where is it!!!????? I've heard/read this is the best place to hook up the fuel pressure guage sending unit, what fittings do I need to complete this and how do I find where to put it?

Boost Guage - Where does this thing plug in to help me see how much boost I'm getting from my supercharger?

Thanks in advance for the help, I'm really clueless at this point!

Schrader valve on my car is the small place on the fuel rail you check the fuel pressure at. Has a smal metal screw cap over it. I can't remember at this time what fittings I needed. I remember it being interesting. :) You can see my L98 setup for the sending unit...



Not sure if yours is the same or not.

I would guess one of the vacuum ports on the intake. Not sure though.

I would mount the Boost Pressure Sensor where your factory IAT sensor is, and relocate your IAT sensor.

Ok, thanks so far. Anyone with LT1 pics/info? Also, what the heck is an IAT sensor and where is it on the LT1? Where to relocate it to? Thanks again.
