FUELAB Fuel Pressure Regulator -6 AN hose Pair up our midpipe withIf you have a 1990 1997 Miata (NA), your car came with a return fuel system from the factory. Since the K series uses a returnless system, you'll need to convert your fuel system to returnless as well. We recommend the FUELAB fuel pressure regulator to do the job. Once installed in your fuel system, you can set the fuel pressure to 60 psi and you'll be ready to go. This regulator uses 6 AN inlets (FUELAB part 51502 1) Note: 1999 2005 Miata (NB)
