fuel pressure question
i just tested the fuel pressure on my 91 integra b18a
With the fuel pressure regulator connected and engine running 38 psi,
With engine running and the pressure regulator vacuum hose disconnected it was at 42 psi. Are these acceptable pressures? I just replaced the fuel filter!
