In the search for the perfect regulator to use in my EFI packages, I couldn't find one. They either didn't mount correctly, have the proper ports or just didn't look good. So I decided to design my own.

I have chosen the use the Bosch interchangeable regulators to cover a wide spectrum of pressures. Most common being a base pressure of 3 bar (43.5psi).

My regulator can be firewall mounted with the stainless bracket that offers enough adjustment for the perfect angle, or through a firewall using a bulkhead fitting. This allows for the return line to be on the correct side of the firewall in Air Cooled applications.
