These fuel pressure gauges measure from 0-15 PSI and are intended for use with carburettor plate and direct port nitrous systems. In most cases (depending on engine configuration and power potential of the nitrous system) it is advisable to have between 5.5-6 PSI of flowing fuel pressure for best results. These gauges have 2-5/8" mounts and are available in several face plate colours.
