Fuel Pressure Gauge

I have no idea what the fuel pressure for an LT1 motor should be, which autometer gauge should I get? 0-15 PSI, 0-30 PSI, or 0-100 PSI??? Also, how hard is it to hook up the fuel pressure gauge (full sweep electric)??

0-100. i know for sure that on LS1s, they operate around around 50, maybe higher. nearly all EFI systems are around that range. the other 2 should be for carbed apps.

LS1 should be around 58-60 lbs

The fuel pressure gauge on LS1's is easy to hook up. I mounted mine on the end of the driver's side fuel rail. I needed some fittings to convert the -4AN on the rail to the 1/8NPT on the sender. I am not sure if LTI's have a threaded fuel rail or not. I can help you find the fittings if you would like.
