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 you r 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.
Aeromotive
Aeromotive has been the standard for high-performance fuel delivery since 1994, engineering fuel pumps, regulators, filters, and complete fuel system kits trusted by professional racers and serious street car builders. If your engine is making big power — whether on forced induction, nitrous, or a naturally aspirated high-displacement build — Aeromotive's catalog has the components to keep fuel supply ahead of demand under every condition.Popular UpgradesThe Aeromotive Stealth 340 and Phantom in-tank fuel pump systems are top sellers for builds that demand consistent flow without external pump mounting. The A1000 external fuel pump remains a proven choice for high-horsepower carbureted and EFI applications. Billet fuel pressure regulators from Aeromotive allow precise adjustability for return-style systems, and complete stealth fuel system kits offer a clean, all-in-one solution for builders who want maximum reliability from a single supplier.What flow rate do I need for my power le...

Fuel Delivery
A properly designed fuel delivery system is the backbone of any high-performance engine build, ensuring the injectors or carburetor receive a consistent supply of fuel at the correct pressure regardless of engine load, RPM, or fuel demand. From factory replacement pumps keeping daily drivers on the road to high-flow in-tank modules supporting 1000-horsepower builds, the right fuel delivery components prevent lean conditions, injector damage, and fuel starvation at the worst possible moment. Modern EFI systems are particularly sensitive to fuel pressure variation, with even small drops causing misfires and power loss under hard acceleration. Whether you are restoring a factory system or engineering a purpose-built race setup, matching pump flow rate and fuel pressure regulation to your injector and engine requirements is essential.

Fuel Pressure Regulators
A fuel pressure regulator maintains consistent rail or bowl pressure regardless of engine demand, fuel pump output variation, or manifold vacuum changes, acting as the pressure control valve that determines how much fuel the injectors or carburetor actually sees at any given moment. In return-style EFI systems, the regulator bleeds excess fuel back to the tank while holding the supply side at a precise setpoint, typically 43.5 PSI for most port EFI applications. In boost-referenced setups, the regulator increases fuel pressure proportionally with boost pressure to maintain a constant fuel-to-air pressure differential as manifold pressure rises, preventing the injector effective flow rate from dropping under boost. Selecting the correct regulator type, pressure range, and port sizing for your system determines how accurately fuel delivery tracks engine demand across the full operating envelope.
