what does this fuel line do????

Hey guys, I was just under the car and realized my friend that was helping me weld my cage in didnt notice a couple metal lines under the car.
I was welding the driver side main hoop and he was doing the passenger. What are the two lines that run along the edge of the car, underneath, and are directly under where a main hoop would be welded on the passenger side?

I follwed one to the gas tank, but it wasnt any main line. It was a smaller line with a hose clamp.

The second one I couldnt follow completly since it was dark out.

They both seem to tuck under the fenderwheel in the right front wheel well.

Any ideas? both lines are crushed and a little burnt.

Thanks
