I copied what the OEM used with my 140amp alternator. (175amp Mega fuse). The fuse is rated for the maximum current carrying capacity of the gauge wire you are using.
If the internal tube is broken on the pressure side of the internal surge tank pump then the surge tank will build a slight pressure and the excess fuel will dump back in the main fuel tank at an accelerated rate. The regulator will never see enough pressure to reach it's set point. That may very well be your issue. Perhaps your replacement unit was someone else's return.
