Build new hoses all the way to the tank. At least in the case of my A1R you have to pull the tool box to get at them and that means lowering the spare, etc. It's not as difficult as it looks though. On my C7 the short hose from the filters to the engine was wet right after I got the truck so I replaced that one and then not longer after I replaced the rest and found what you see above. They just rot and fall apart and my truck is only 15 years old.
