Aeromotive X1 Series Internal Conversion Kit, .313" seat (red), configures X1 regulators to a 35–75 psi operating range. It lets technicians swap internal components to match the regulator to EFI or carbureted fuel pressures rather than replacing the entire regulator. The X1 platform retains a 1/8" NPT gauge port, a 1:1 boost reference and larger -08 AN ports for increased flow.
