Metal fuel line replacement - 1984 K20 Chevy Suburban

[62ChevyC60Wrecker]

The truck is originally a Texas truck. All the rust the truck has is only "surface" where the trim that "was" on the Suburban either fell off or was removed by the original owner. The only "cancer rust" is on the outer rocker panel for the back door driver side; I have the rocker to replace rusty rocker. I just need to get to a HS classmate's body shop; she has everything I need to replace it with. She's been in the industry (body work) for the last 30 years. The lines I am replacing are all the rubber lines and one of the vent lines for the filler neck, as I couldn't remove the clamps to remove the one hard line that went between the filler neck and the tank which is fine with me.
