From Stock Eliminator to Pro Mod, the Aeromotive A2000 is a versatile force to reckoned with and stands alone as a 'big' carbureted fuel pump. The A2000 flows enough fuel to support the world's quickest nitrous Pro Mods on gasoline, and is the industry's only fuel pump that uses a true diaphragm controlled, adjustable bypass valve, integral to the pump. This design dampens pressure spikes, delivering smoother, more controlled flow and pressure, ensuring more consistent E.T.s and win lights. High torque, low RPM motor design delivers more than 350 GPH free flow, while developing less current draw than any other pump in its class. Adjustable diaphragm bypass valve outperforms ineffective poppet designs, minimizing flow loss and pressure fluctuation to the regulator and carburetor. ORB-10 inlet and outlet ports with ORB-8 return and 1/8' NPT gauge port. Proprietary seal design eliminates leakage. Alcohol compatible. Multiple bolt patterns on the bottom of the pump body fit many chassis mounting options. A2000 Drag Race Carbureted Fuel Pump.
