Tanks Inc-who's using it for non fuel injection and a few other questions

I installed it in a 71 cuda with 472 hemi and 2 four barrels and then converted to fitech f.i.. With the carbs I ran a fuel pressure regulator to keep pressure at 6 psi.. Also ran a return line and had no problems at all. The gauge is pretty accurate but it seems to move gauge a lot more than oem float. Up & down hills is when I notice gauge moving more than with OEM float. Not a big problem though, settles down on level road.
