I wouldn't think that the diameter of the line would have much effect on the reading. Are you running a box along with your nozzles? because I could see it starving for fuel if you were and weren't running a bigger pump. Either way, 7psi is not a good number, and Zero is far worse. I've talked to people that consider 8psi under load to be dangerous.
