 Put everything back together. Fuel still leaks out rear carb fuel bowl vent. Engine not running..key on run. Takes a minute or two for then fuel runs out the vent steady. New fuel pump was listed as 2.5-3 psi direct replacement...tested at 5 psi same as what I had originally. Would the pressure be less with the engine running?

So I am back to where I started. The floats..floated. Jets replaced with Grose...I ordered a pressure regulator to bring it down to 2.7 psi. I hope that solves the problem.

Did the car have some pressure regulator hidden in the fuel line somewhere originally? The PO replaced the tank and the rubber lines...if there is some regulate its gone now. I think I remember reading about some kind of thing the the line to regulate pressure?
