From carbureted to EFI pressures, naturally aspirated or forced induction, the X1 Bypass Regulator is designed to span the entire range of low and high pressure applications providing the dependable fuel flow and pressure control you've come to expect from Aeromotive.
Using the X1 regulator today for a carburetor or EFI, you can easily switch platforms back and forth at will, without having to purchase another regulator. Simply get the correct conversion kit for your pump and pressure range (sold separately) and you can swap out the internal parts while leaving the regulator mounted and plumbed as is.
Replace original X1 Series regulator internals with the conversion kit of your choice and you have a regulator with vastly different characteristics. While versatility is one of the X1s 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 tomorow. 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.
