TPI fuel pressure regulator
They would work on 3.1's correct? Would 45 PSI work on a 3.1 with full exhaust? or would it need to be more,like 47-48?

It's the same part for V6 and TPI.
Here is my fuel page, it has the FPR that I used on my V6 with the summit part # too.
The stock fuel pressure is 43.5psi, turn it up if needed.

All you need is to put it on there and turn it up untill you run lean then you will need new injectors then a pump as some point. Maybe not with with a V6.
