Hi Jerome,

A dead-head regulator does not require a return line to the fuel tank/cell. BG may be lumping all mechanical pumps into the same category. There are many racing pumps (belt driven) that must have a bypass line to the fuel tank or the pump will burn up the belt or spit it off.. If your fuel pump is driven off the camshaft eccentric (mounted on the timing chain cover/block) you will be just fine with the cheaper Dead-head regulator.
