Regulator

Replace original X1 Series regulator internals with the conversion kit of your choice (Part #?s 13013, 13014, and 13015) and you have a regulator with vastly different characteristics.?While versatility is one of the X1?s greatest assets, it is far from the only new design feature. Utilizing larger (3) -8AN ORB inlet/outlet/return ports to accommodate increased flow, at the same time Aeromotive reduced overall size and the weight by 33% (compared to Aeromotive 13109 regulator). The new X1 design eliminates the compromise common to other convertible regulator designs, with the optimization of all internal components including the diaphragm/poppet, spring and bypass seat, the X1 delivers all of the performance and features you expect from an application specific bypass regulator, regardless of what you decide to do with your induction system tomorrow.?Above and beyond the expected performance, you still have the amenities like a 1/8? NPT gauge port and 1:1 ratio boost reference port for forced induction applications. Base fuel pressure adjustable from 35-75 PSI. Vacuum/boost reference capability. 1:1 rising rate for forced induction engines. Gasoline, ethanol, and alcohol compatible. (2) ORB-08 inlet/outlet ports on the sides. (1) ORB-08 return port on the bottom. (1) 1/8? NPT Gauge port with plug. 1/16? NPT Boost port with 5/32? hose barb. 0.188? bypass with matching spring and poppet. Handles up to 150 GPH with AN-08 return line. Suitable for any Aeromotive pump up to A1000. Mounting bracket included.
