Go Fast Bits FX-S Fuel Pressure Regulator (Part Number: 8051)

If you're looking to enhance your engine's performance, the Go Fast Bits FX-S Fuel Pressure Regulator, part number 8051, is a solid choice. Designed as a direct replacement for the Bosch regulators that clip into the fuel rail, this compact unit makes upgrading your fuel system straightforward and effective.

When you push your engine to new heights, ensuring that your fuel system can keep up is crucial. Many enthusiasts find that simply upgrading the fuel pump leads to excessive fuel pressure, particularly at idle. The factory Bosch regulators often struggle to support larger fuel pumps, especially in turbo E85 setups that require high fuel flow rates. The FX-S 8051 addresses this issue seamlessly.

Instead of replacing the entire fuel rail or using an adapter with a separate regulator, the FX-S 8051 can be clipped into place, allowing you to run a larger pump without the hassle of extensive modifications. Plus, if you need to tweak the fuel pressure, this regulator is adjustable from 1.4 bar to 5 bar, unlike the fixed-pressure Bosch alternatives.

One of the standout features of the FX-S 8051 is its compatibility with various fuel types, including pump gas, ethanol, and methanol. Customers have noted that the soft Teflon valve seat ensures a reliable seal, which helps maintain fuel pressure even after shutdown, making for easier engine starts.

The double-layer diaphragm is another notable aspect, boasting twice the reinforcing material found in standard regulators. This results in a burst strength that exceeds 1000 psi, giving you peace of mind when pushing your engine's limits.

Customers have shared their experiences, with one stating, "The installation was a breeze, and I noticed an immediate difference in my fuel delivery. No more stalling at idle!" Another user mentioned, "I appreciate the adjustability; it really helped fine-tune my setup for E85." These testimonials reflect the reliability and effectiveness of the FX-S 8051 in real-world applications.
