    Carburetor Regulators

    Same use as 4-port but also has a return line. For converting an EFI vehicle to a carburetor but using the EFI fuel pump and return line. Also, this type of regulator should be used in conjunction with any high-volume electric pump to avoid overworking the pump and heating up the fuel. At idle or low engine speeds, a high-volume pump is attempting to pump way more fuel than the engine can use. With a bypass regulator, all this excess fuel is returned to the tank. A 5-port bypass regulator would commonly be used where dual inlet dual four barrel carbs are used and the four carb inlets can be plumbed directly from the regulator.
