FUEL PRESSURE REGULATORS (Carburetors/EFI)
Standard or Dead Head design for Carburetors
The AR2052 3-port fuel pressure regulator is the most popular design due to its simple inline installation, adjustability and high flow rate. The AR2052 regulator uses a standard or dead head design making the installation very simple and straight forward, since plumbing a return line back to the tank or fuel cell is not required. The AR2052 features a 2-pcs anodized billet aluminum body. The large top mount adjustor screw and lock nut make adjusting the fuel pressure a quick and easy task. The extra large diaphragm produces a very stable fuel pressure over a wider than normal range of 4.5 to 14 PSI, without creep or fall off. The AR2052 regulator features a single bottom inlet and twin side outlet ports, all with 3/8” NPT female treads, allowing it to be used with both single or multiple carburetor applications. The AR2052 fuel pressure regulator also features a 1/8” NPT female threaded port for mounting a fuel pressure gauge. Compatible with gasoline and Ethanol bends including E85. Not compatible with Methanol fuels. AR2052 comes complete with mounting bracket.
Return style for Carburetors and EFI
The AR3052/AR3072 adjustable 4-port fuel pressure regulator is designed for use with electric fuel pumps. The bypass or return design eliminates pressure creep and vapor lock, reduces fuel pump noise and increases pump efficiency and life span.This is accomplished by allowing excess fuel that is not needed to power the engine under load, to return to the tank. The AR3052/AR3072 features a 2-pcs anodized billet aluminum body. The large top mount adjustor screw and lock nut make adjusting the fuel pressure a quick and easy task. The extra large diaphragm produces very stable fuel pressure over a wider than normal range without creep or fall off. The AR3052/AR3072 features extra large 3/4”-16 SAE threads (-8 AN O-ring port fittings) side inlet and bottom return ports, with three 3/8” NPT side outlet ports and one 1/8” NPT gauge port. Boost /vacuum reference port maintains constant fuel delivery based on engine loading. Compatible with gasoline and Ethanol bends including E85. Not compatible with Methanol fuels. AR3052/AR3072 comes complete with mounting bracket.
