Hey guys I recently picked up an 03 2500hd with higher miles and being from Delaware the salt has eaten up both the brake lines and fuel lines. I have replaced the brake lines and am on to the fuel lines now. I plan to boost the truck in a year and build my own turbo kit with hopes for over 600hp so my question is how much can stock fuel lines hold, I know some people have said that they have seen them hold quite a bit and if that is true then I will leave them for now. If that is the case, does anyone have a recommendation of a place to get good stock line replacements?
