[47 Fasttoys]

Depends on the year, If a return style fuel rail yes it uses a vacuum line to the regulator. very short molded piece of rubber tube which connects to the intake. The later use a regulator at the pump.

Mine is a return system and that little vacuum line and adapter to the small line on the rail is what I am missing
