Fuel Pressure Regulators
SPA Turbo USA offers a wide array of adjustable fuel pressure regulators that replace OEM regulators in the factory EFI systems. Our OEM replacement regulators attach to the factory fuel rails using OE style retainer clips and bolts. Internally, the regulators use a fl oating ball seal that guarantees even pressure. In most cases the fuel pressure can be adjusted/tuned from 10 to 100 psi on a 1:1 boost reference. We also offer universal units with an 14:1 boost reference for more extreme horsepower applications.
