Anyway, remeber the main reason for fuel return on EFI engine: to regulate
the pressure to the injector(s), not to cool or anything else. So, I think
that if you return it above fuel level should be OK. New EFI engines do not
use a return line as the fuel pressure is regulated inside the fuel pump.
