Fuel line routing through front fender well

FWIW....here's what I did on the avatar car.

I ran 3/8" NiCu hard line inside the frame rail from my elec pump, through the trans cross member, then in the RF wheelwell for just a bit. It turns upward and enters the bottom of the regulator that is mounted on the "horizontal" part of the inner fender. The regulator then sends a small line to the cowl-mounted fuel pressure gauge along/under the firewall seam and the main fuel feed line to the rear of the carb to its dual inlet. You can see the regulator in this pic and the carb feed line in the 2nd pic. This minimizes heat in the fuel line and so far, I have not needed a cool can on the car.
As for the bit of line exposed in the wheelwell, it's tight to the body line and can be covered with some wire loom or Kevlar loom as needed. I have not done that as this car doesn't get out on dirt roads or in bad weather!!
