fuel This is my new progressive 2:1 fuel pressure regulator and fuel hoses. I also had to replace the spring in the regulator. It was designed for 45 psi fuel pressure. As you see I also moved the air filter to a better location.
Fuel pressure is set to 13 psi on the stock regulator (blue).
At atmospheric pressure the progressive regulator (pink) takes command and
starts to raise the fuel pressure. At 10 psi boost the fuel pressure over the
injector (dotted yellow) is 23 psi.
