DW Regulators Provide the Quality, Precision, and Reliability that Your High-Performance Fuel System Requires to Deliver Stable AFR and Optimum Performance.

Adjustable fuel pressure regulators are simple mechanical devices that have not changed much over the decades and are often taken for granted. However, if you have ever experienced a failed diaphragm, fluctuating fuel pressure, or hot/cold start issues that inferior regulators can cause, you will appreciate the DWR1000 and DWR2000 adjustable fuel pressure regulators.  Development of the DW regulators started with a comprehensive evaluation of the popular regulators already on the market. DW regulators were benchmarked against 5 of the leading regulators on the market and designed to outperform all across multiple categories. 


Designed with Ethanol in Mind

DW regulators were designed to be 100% compatible with ethanol-based fuels. The corrosive nature of modern ethanol containing fuels will create significant issues for regulators that are not designed specifically for use in this environment. DW regulators utilize stainless hardware, nitrile-fiber diaphragms, anodized housings, and are of-course 100% brass free in their construction. 

Precision Pressure Adjustment

DW regulators incorporate several design features that allow precision pressure adjustment ranging from 30-100 PSI. The ball-bearing adjustment mechanism combined with a 2 psi-per-turn pressure ratio makes dialing in your desired target pressure an easy task. In addition, the massive 45mm diaphragm maintains that set pressure with unrivaled accurately.

DWR1000 and DWR2000 Meet all Your Fueling Needs

DW offers their adjustable fuel pressure regulator in 2 different sizes. The DWR1000 is designed for 300-1000hp and features -8 ORB inlets and -6 ORB outlet. The DWR2000 is designed for 750-2000hp and features -10 ORB inlets and -8 ORB outlet. Both regulators feature a multi-positional mounting bracket, integrated 1/8” NPT gauge port, and semi-compact 60mm footprint for maximum installation flexibility.  A 0-100psi pressure gauge is also available.
