Auto meter Electrical gauge?'s

I searched and came up with nothing use able. Here is my situation; I have swapped a bone stock LQ4 into a Toyota Tacoma and bought all Autometer electical gauges for my instrumentation and Have a Sand and Street Performance wire harness. My question is where would I place the sending units for the gauges for the fuel pressure, oil pressure and water temp? The sending units are all either 1/8" NPT or 1/4" NPT. Any and all information is appreciated.

you need this for the fuel pressure sensor http://i17.photobucket.com/albums/b6...ueladapter.jpg

+1 Use the casper fitting to grab the fuel pressure reading off the fuel rail's shrader valve.

Thanks! I haven't been able to find anything like that so far.
