TURBOSMART FPR KOMPACT FUEL PRESSURE REGULATOR – UNIVERSAL 1/8 NPT (SLEEPER)

The factory in-rail regulator is a common bottleneck on mildly modified turbo cars. The Turbosmart FPR Kompact (TS-0404-1015) is an all-black, billet fuel pressure regulator built to replace it, offering adjustable, class-leading fuel control in a small footprint for builds up to around 800HP.

A CLEAN UPGRADE FOR OE AND MILD BUILDS

Where the stock regulator is a fixed, non-adjustable unit, the FPR Kompact gives you a universal 1/8 NPT inlet and outlet, making it a drop-in upgrade for OE and mildly modified fuel systems. It's the simplest way to gain accurate, adjustable fuel pressure control without a full aftermarket fuel rail conversion.

PRECISION WHERE IT COUNTS

Inside, a stainless steel valve seat and Milspec diaphragm deliver a true 1:1 pressure ratio and fast response, so your fuel pressure tracks boost accurately from idle to full throttle. It's compatible with all fuel types, including E85.

Key Features:

• Adjustable 35–80psi Range – Suits OE-level and mild bolt-on upgrades to ~800HP
• Stainless Steel Valve Seat – Suitable for all fuel types including E85
