The new DeatschWerks fuel pressure regulators provide the quality, precision and reliability your fuel system deserves. Both the DWR1000 (1000hp) and DWR2000 (2000hp) come with dual AN inlets, and a single bottom mounted AN return. Construction materials are stainless steel and anodized for ethanol and methanol compatibility. A ball-bearing mechanism allows for smooth and accurate base pressure adjustment. The large 45 mm fiber-reinforced Viton diaphragm is compatible with all fuels and provides a large surface area for increased response and precision. Regulators come with a multi-positional mounting bracket to maximize installation options, and a 1/8 NPT gauge port (sold separately).
