New guy here. Rear fuel tank works fine. Tank switch works, as truck dies shortly after switching to front tank. Previous owner had cut and plugged front fuel tank lines 6" from the tee at tank. Lines have rotted, now can't plug well enough to stop leaking, time to replace. It appears the entire fuel line system will need replaced, as the braided section is made into the main metal lines running up the frame rail. Anyone done this before? Have anything I should look out for? Supplier for fuel line assly? or just junkyard? All help is appreciated.
