Dual fuel tank fuel line

[ben82k10]

I have an 82 k10 with dual tanks. Currently the drivers side is the only one working. The guy I bought it from said it needed a new fuel tank selector valve underneath. I have that, but I didn’t realize until I got under there it doesn’t have the fuel line from the valve to the tank. What lines/hoses do I need? I’m having a hard time finding it. I see a bunch of stuff for efi, ls swaps, metal, rubber. This still has the original 4.1 250 inline 6.

Find a schematic. For an original 82 you have 3 ports in each tank. Feed, return and vent. March those up and let er rip.
That said, sounds like you don’t have any experience with these trucks.
IMHO, sure it’s fine to patch something fuel related to get it running. But if you want to be done with it, do it right, replace everything and enjoy another 20-40 years of trouble free dual tank use.

100% new to this. I know pretty much nothing about this and these trucks. I bought it because I loved them as a kid, and look forward to learning. Learned and am learning a lot so far.

I'd start here.... they may not be the exact line but it will get you close.

I believe 3/8" for feed line (tank output to valve input), 1/4" for return (valve return to tank inlet/return) and 5/16" for vapor (tank to canister in engine bay, if its still there)

I recently fixed my dual tanks on 85 c10 and fuel lines from LMC worked great. I would replace the fuel sending unit on that side while you are at it.
