Our fuel regulators are designed to fit most vehicle's EFI systems. They are compatible with gasoline, E85, and alcohol/ethanol, but not with diesel fuel. (Nylon braided fuel line is not compatible with E85.)

The pre-installed spring supports a pressure range of 20-75 psi, while the replacement spring supports a pressure range of 75-120 psi. Adjust the set screw on top to get the desired pressure, and change to the replacement spring if a higher pressure is needed.

When installing the fuel regulator's NPT pressure gauge port, please use thread sealant tape for sealing. Professional installation is highly recommended.
