To return fuel or not to return fuel?

First, the fuel return was engineered for a purpose.
This being so the fuel pump is not "dead headed".
This condition exists when a pump tries to push
against a closed system.
This condition will exist in your fuel system when at idle.
I have read where some people get away with it,
but for how long has not been reported.
If the float needle seat or valve is not up to the task
carb dumping can result, it may not be enough
"passed gas" to cause problems
but why take chances.
The engineers at Subaru may not always score tries-
but most times they do put the ball up for points
on a free kick.
The filter you speak of with the return out of the top is a "vapor separator"
The true fuel return line is connected close to the carby fuel inlet.
The Weber DG series I have have a return built into the fuel input port.
You can use a "T" with a restrictor placed in the return leg.

is the Weber
my quess - given Holley was designed for the
US market is -- no
A "T" fitting with a restricter of sorts would be
an EZ way to solve the riddle
Email me if you want and I'll show you a couple ways
I have done this.
