95 gst, you can run 50 psi base, and you will see 70 psi at 20 psi boost. The reg is linear, so it moves up 1:1 with the boost.
You can actually run up to 60 psi base on the stock spring, and more on the extra spring that comes in the kit.
As for the screw in gauge, the new designs will have them, but I will say, this is just a extra over the top option. Meaning, the reg in it self is plenty good, but to be able to put a gauge off it is even better.
But if things do not work out for some reason on the screw in, its gone. It is not as important to have the gauge off it as just a solid reg that will control the pressure problems. All adjustable fuel regs I have seen so far do not have the custom bolt on with a fuel gauge. The big plates and so on might, but not the custom applications. So, it really is not the regs function to be a reg and a fuel gauge host. So if it works, even better, if there is a hint of something, gone.
There will be more ways to get the pressure near the rail, the filter one will not be the only way, our feedline will have a 1/8 th npt port right on the other end of the rail.
