on systems that have a return line
that extra unused very heated fuel goes back to the fuel tank , heating the fuel in the tank
which causes heavy duty evaporation and pressure build up in the fuel tank much of that pressure and HC
can
be vented
to atmosphere
because most systems are not designed to handle that scenario
fuel vented to atmosphere does not increase FE as it is
wasted
10% improvement .... not very likely

your right!!!!!!!!! but what if we bypass the return line?
