Fuel line routing to tank

[rockdogz]

How did you guys route your fuel (and fuelpump wiring) lines to the rear? I started outside the frame rails at the front of the car, then crossed over to inside the frame rails about halfway through. However, after installing the exhaust, the muffler is 1-2 inches away from the electrical and fuel lines, and I've wrapped the lines in heatshield to protect them. How did you do it?
