I bought a little tube bender and I used all standard lines from a parts store. You should remove each line and keep it in original shape to help make the new ones. Sometimes you can't buy a line that is the correct length. Just get one a little long and form a loop to take up the slack. You will need to clean up all your blocks.
You can pressure test your system before ever driving the truck. You can generate a lot of force sitting in the driver's seat.
