Fuel Pressure help
Now thinking that the fuel that is being dumped by the Qjet into the engine at idle is due to too high fuel pressure.
1. Is 7.5 to 8 lbs too high for the qjet?
2. I have a new Paragon A.C. Delco pump - do I replace the pump keep the car stock looking and try to get a 6 psi pump? and if so how do I guarantee I get one at 6psi.
3. Do I just install a regulator and be done with it?

Re: Fuel Pressure help (kostutsman)
Don't know what you've done so far to determine this, but a sticking carb float can cause same. Most needle & seats will tolerate a few extra lbs pressure without dumping. If all is well with carb, and you want to regulate press, install regulator.
