Trying to find out if the GTO has a return or returnless fuel system. Anyone out there know?
Makes a big difference with the Fuel tank pressure.

Return system: FTP = 60
ReturnLESS system: FTP = 55

The return is at the fuel filter. There is just one line from the filter to the rail that supplies fuel, the rest are vapor lines.
