Fuel line from regulator to carb

I'm in the process of running a new fuel line on my Demon. The car will be raced. I'm using a dual feed line with guage on my carb (Proform 750). I need to get from the regulator, which is mounted on the right fenderwell to the carb line. I was thinking of running a braided line to connect them , but, according to IHRA rules, the line can't be more than 12" in length. I have about 16" to cover. I'm hooking up this way for now, may go to seperate lines to the fuel bowls from the regulator in the future. What are you guys doing if you have a similiar setup ?Should I run a piece of Hardline out of the regulator to cut down on the amount of hose that I'm using?
