Aeroflow has taken its forward thinking knowledge to the street, manufacturing a wide range of race quality products to improve street performance and dependability. Introducing to the growing range of Aeroflow Performance fuel regulators is the Carb to EFI conversion fuel pressure regulator. This fuel regulator allows carb owners to convert to EFI with the use of the same regulator. Simply change the internal spring and make the conversion a breeze. With a carburettor pressure spring installed out of the box which allows adjustability of 3-20 psi, simply unscrew the top half of the fuel regulator and install the supplied EFI spring which will now allow adjustability of 20-60 psi. Being a compact design with height of only 115mm, diameter of 53mm this can be installed anywhere with the supplied billet mounting bracket. Featuring 3 x -8 ORB female ports for a perfect O-ring seal and a 1/8 NPT port up front. Designed for applications producing up to 800hp (596kw) where space is at a premium and made from billet 6061 T6 aluminium these regulators are an ideal upgrade for carb & EFI fuel systems. Ethanol, methanol & unleaded compatible. A mounting bracket is included. This regulator features a vacuum/boost port and fitting in the cap which, if connected to your intake manifold, will reference fuel pressure to manifold pressure. It works on a ratio of 1:1 with PSI, raising fuel pressure with boost and reducing it with vacuum. If unused, please do not block off. Capable of supporting applications up to 800hp, the Aeroflow Compact Carb & EFI Regulator can handle high-flow EFI fuel pumps and the most aggressive street machines; especially those looking for a cleaner, lighter solution where performance is critical or where space is a premium.
