Fuel piping question

Finally completed the fuel lines all the way to the carb and ran the return back to the tank. I still need to make a bracket to support the fuel filter just from the regulator to the carb but other than that I am done with fuel until I install the 2x4 set up. I ended up using 1/2" line all the way. Here are the finished pics under the hood area.
