new fuel cell

going to mount a plastic Jegs or summit fuel cell in the wheel well and was wondering about running rubber fuel line just to the old stock metal line. I know the rules say I can only have one foot of rubber line from the metal fuel pump line to the carburetor, but can I just run regular rubber line from the fuel cell to the old fuel line ? I'm sure it's just going to be a couple feet or so. I'll probably have an electric fuel pump between the fuel cell and the old fuel line to help things along also.
