When do you need to replace the fuel pump regulator?
You only need to replace a fuel pressure regulator if it’s failed. Simple fuel pressure testing will determine that. Pump puts out 55-60 psi and regulator knocks it down to 30-ish. If PSi post-regulator is higher than 32-34, than regulator is bad.
What to do if your Harley Davidson has a fuel leak?
In the early stages, you could get the symptoms you descibe, due to low fuel rail pressure. Check for intake gasket leak. Spray wd-40 around intake at jugs.See if you get any change in rpm. Could this be a venting problem?

What happens when voltage regulator goes bad on Harley Davidson?
With a faulty regulator, none of the normal lights will illuminate. What’s happening is that there is no power getting to the instrument cluster, which is why it’s disabled.
What causes low fuel rail pressure on a Harley Davidson?
This could compensate for low fuel rail pressure, until the engine warms up. Your low fuel rail pressure can be due to a sticking pressure regulator. The pump is a constant pressure, but the demand changes, hence the pressure wants to vary. The pressure regulator bypasses all un-needed pressure/fuel back into the tank.
