The approach taken for the DWR1000 adjustable fuel pressure regulator is not to reinvent the wheel, but simply to make a better wheel. All the best aspects of the existing regulators on the market were included in the DWR1000, but in addition, improvements were made in materials and design to culminate in the best all-around regulator available to date. Designed and tested specifically for ethanol compatibility – Many popular regulators on the market today contain brass internals, which can corrode and weaken when used with e85. The DWR1000 was designed from the ground up with e85 in mind and is constructed with 100% e85 compatible materials such as stainless steel, anodized aluminum, and nitrile. The DWR1000 is ideal for the 300hp to 1000hp range and able to handle 500lph of flow. It comes in your choice of anodized black or titanium finish, and an optional 0-100 psi mechanical gauge is available. * Fiber Reinforced Viton Diaphragm * 100% Stainless and Anodized Internals * 45mm Diaphragm * Ball-bearing Adjustment * Dual Inlet * 1/8 NPT Gauge Port PartNumber : dw6-01-G Description : Mechanical Fuel Pressure Guage Price Group : P2 Web Site Category : Fuel Pressure Regulators Web Site Group : Fuel Pressure Regulators Diameter : 1.5in Face : White Range : 0-100psi Thread : 1/8 NPT Gauges & Pods::Gauges
