Fuel return line

[Frederic Breitwieser]

The purpose of the return line is to allow the fuel pressure regulator on 
the efi setup to pass the extra fuel somewhere.  The fuel tank is a logical 
choice since the bulk of the fuel is there, and its not a pressurized 
container.  Generally.

Feeding the return line to just before the fuel pump draws from generally 
can cause some cavitation in the fuel line post-fuel pump as the tank draw 
mixed with the post regulator ::crash:: in the line.  Just spilling it into 
the tank is cleaner.

Also, fuel line is pretty cheap :)
