If the return line is below the surface of the fuel it may show a slight amount, and the further down in the fuel it is the more pressure it will show but still not much.... Dunno....
While we are on the subject of fuel return I see no reason that the return line couldn't be fed back into the fuel pump inlet with a tee or wye fitting. (I think a wye would be better for the flow) I was going to try this on my '67 Panel Truck but I had to buy a new fuel tank and it had a return line fitting on it. Has anyone tried this????

Too much heat introduced by recirculating the same fuel. No way I'd do a setup like that. In tank pump with correct return plumbing is the way to go for a N/a LS.
