A freind of mine with one of the nicest 58 T-Birds on the planet, has a brand new 650 Holley on his brand new 390 FE mill. He's been plagued with gass dribbling from the secondaries once he shuts it off hot - it runs fine but it loads up bad just sitting still... We've adjusted the floats three times now and the problem just keeps coming back to haunt him.

Is it possible for a new Ford OEM mechanical fuel pump to make enough pressure to upset the floats on a new Holley?

I thought at first the gas might be boiling, but it's been 48 degrees outside lately, and the fuel line is a long way from the exhaust manifold.

Any input before we dive into this thing, would be appreciated.

you will probably find a little piece of foreign object stuck to the inlet needle, look at it real close.the other posibility is the float is too high, adjust it about 1/16" lower and see what happens.

Hey Bob, yeah thanks for the idea... Every thing is new on the carb side of the filter, incuding the fuel rail. I can just imagine a tiny flake of plating sitting in there somewhere. We will pull the float bowl and put everything under the microscope. Thanks.

As you mentioned in your first post, too much fuel pressure could be the problem, but I would think you'd experience the problem on both sides of the carb. Worth checking though.
