Where is everyone installing their regulator? We have two inline filters, one right outta the cell and another before the injectors. Does it go between the two or after the last one prior to injectors?

If you run a return regulator (most common in race situations) it goes after the rails and feeds the cell/surge tank return. If it's a closed cycle then it'll also go after the rails but doesn't have a return (but the pressure is regulated by pulse width modulation of the pump drive)
