Get Trouble-Free Fuel Pressure Management with FUELAB Fuel Pressure Regulators

FUELAB Fuel Pressure Regulators keep fuel pressure in check so your carbureted or EFI engine gets stable, precise, and controlled fuel flow for maximum power. The regulators work with gasoline, methanol, E85, diesel, and flex fuels. 

Features include:

  • Precise fuel pressure management at all RPMs
  • Fine thread pitch adjuster for precise pressure adjustment
  • 1/8-inch NPT port for an external pressure gauge
  • 1/8-inch NPT boost/vacuum reference port
  • Made from billet aluminum with your choice of black, red, blue, gold, purple, or green anodized finishes (except 5010 series)
515 Series Regulators have a bypass design with a -6 AN return port on the bottom. Choose from the -6 AN or -10 AN inlet and outlet ports. They are available in models to regulate between 1 and 125 PSI. Mounting bracket with stainless steel hardware included.

525 Series Regulators have the same features as the 515 Series, but with -6 AN ports only. The return port is in line with the inlet and outlet fittings, making them ideal for use in cramped spaces.

555 Series Regulators are non-bypass style with an advanced poppet design to smooth out fuel pressure spikes, plus a no-creep soft seat that is methanol- and E85-compatible. They have one -8 AN inlet, two -8 AN outlets, and a -6 AN return port. They are available in models to regulate between 1 and 65 PSI. Mounting bracket with stainless steel hardware included.

575 Series Mini Regulators work just like the 555 Series regulators but are smaller and 50 percent lighter. They have -6 AN inlet and outlet ports.

5010 Series Regulators have a bypass design with -10 AN inlet and outlet inline ports and a -6 AN return port on the bottom. Available in models to regulate between 4 and 90 PSI and a mounting bracket with stainless steel hardware is included. FUELAB recommends using these regulators with their Velocity Series Lift Pumps for diesel applications.
