Message I was thinking that as you pass 0 psi and enter positive manifold pressure, the FPR keeps adjusting as manifold pressure increases.

In reality, is it that at 0 psi and over the FPR configuration is static, and that the fuel pump speed/fuel controller is at that point what keeps the pressure up where it should be? If that's the case then I guess "consistent at 51psi" means at 0 psi manifold pressure, but that the actual pressure increases as the fuel delivery system works harder under load?

Maybe?
