Fuel restriction w/ 6an line?

Here's a pic of the way my regulator and pressure gauge is set up. Obliviously I have a dual feed carb so it's going to be slightly different than yours but should give you the general idea.

The inlet lines are a kit from AED. They were kind of a pain to fit. Initially the regulator was on a bracket that attached to the RF carb stud but it didn't work because the regulator was hitting the valve cover and the fittings/hose end for the line from the pump was hitting the intake runner. Ditched the bracket and it all came together without clearance issues because I was able to set it at a slight angle. Its plenty rigid without the bracket.
