One thing I meant to add, which I thought of after doing this whole job, is that the fuel lines are a major PITA. Expensive, tough to source, unwieldy to replace, and the main reason to drop the tank.
However unlike the brake lines the fuel lines are low pressure, mostly plastic coated, and actually only really rust in two places... right at the end in the engine compartment, and where they make the transition from horizontal steel to vertical plastic (next to the fuel tank). So, if I had to do this over again, I would consider simply cutting out the rusty bits and splicing in some replacement fuel hose. Could be done relatively easy in place.
