instaling air fule, fule pressure gauges

[trinitron]

how hard is it to install in a 3.4 camaro.

Both are very simple...there is a fuel pressure relief valve on the top of the fuel rail. You will need to remove the schrader valve in it and at that point, you can use it to get your fuel pressure.

For the A/F ratio gauge, the 3.4L V6 use single-wire O2 sensors so simply tap into one of those wires.
