Vall I’ve been using the Mallory 140 kit with regulator and bypass. This requires a return line to the tank. I put this pump on three vehicles. Coupe from 2010. Camaro since 2007 and the MG since 2012. None of which failed since installation.
Now watch it fail on me. Lol. It is pricey but I was told the return makes the pump run cooler and with less effort. Making it last longer. So far so good.
