Product information

Nuke Performance FPR90 Fuel Pressure Regulator: Stable fuel delivery for all applications from 300 – 1400hp.

The Nuke Performance FPR90 fuel pressure regulator is a tried and true fuel pressure regulator trusted among motorsports teams worldwide. It is specially developed for extreme power output, maintaining a steady fuel flow for engines ranging from 300 to 1400 horsepower.

 Safe for petrol, methanol, and ethanol
 Adjustable up to 90 PSI (6.2 bar)
 1:1 boost reference
 Stainless steel mounting bracket
 AN-8 fittings included
 Made in Sweden

The internal fluoronitrile diaphragm is designed to stand up to the destructive properties of all fuels, including methanol and ethanol, ensures a fast response rate, and maintains steady fuel delivery during dramatic changes in fuel demand.


 1:1 boost reference with precision pressure adjustment
The FPR90 utilizes a hardened steel ball with a replaceable steel seat to allow fuel pressure adjustments up to 90 PSI (6.2 bar) by simply turning the hex screw.


 Ethanol-proof membrane rated for well over 1000 hp
Fuel pressure rises on a 1:1 ratio when referencing boost with precision pressure adjustment. The fuel pressure is dialled in using the set screw on top. With the dual inlet design, you choose between a left or right inlet or dual inlet for V-engine setup. 1/8" NPT thread faces forward for easy to read fuel pressure gauge/fuel pressure sensor installation.

The stainless steel mounting bracket that´s included ensures a safe, tight mounting of the fuel pressure regulator. Fits most engine bay compartments thanks to its clever design which holds it away from the surface it is mounted upon.


 Comes ready to install, with all needed fittings included
Delivered with an AN-8 to AN-8 Male (3/4 UNF thread) inlet fitting, an AN-8 to AN-6 Male (3/4 UNF thread) outlet fitting, a single AN-8 Plug (3/4 UNF thread), and a quick-connect 6mm pneumatic vacuum fitting, that uses the same system as the other items in our vacuum range.

Additional AN-6, AN-8 and AN-10 are sold separately.
