Decided to replace my electric fuel pump due to uncertainty of the type and the fact that the fuel lines were somewhat pinched from the fuel line routing. Also wanted to be sure I was feeding the dual Weber 36 carbs with the correct pressure.
So I came across the info on this website:

and went ahead and purchased and installed a Carter 4070 pump as suggested.
Now it seems that the carb is running very rich at idle since I now have to turn in idle mixture screws (lean it out) to bring up the rpm and open the butterfly's by a few turns just to keep it running.
So my question is whether anybody else has tried this pump and if so, have folks always used a pressure regulator to bring the pressure back down. The pump is rated at 4-6 psi (guessing I am seeing the higher end at 6). Have not actually put a pressure guage on the line yet but the before/after symptoms point to too much fuel.
Is there another in-line pump that offers a better alternative?
Thanks
Drew
