How Hard is it to replace a Fuel Line
I recently purchased a 1987 Samurai. The body is in excellent condition, however, the car has problems idling and it stalls. So far I have advanced the timing and sprayed chemtool B-12 carb cleaner into the carb. After the car sits I can start it up and it idles fine. However, if I then turn the car off and on a few times the idle becomes worse and the car starts to stall. I went out and purchased a new Dist. cap, rotor, ignition wires, air filter, Fuel filter, and spark plugs but have not had the time to put them in yet.
Today when I was looking to see where the fuel filter was located I noticed that my fuel line is in very poor condition. It has many cracks in it and is rusted along its entire length. There is one place near the rear wheel where the crack is big enough to leak fuel. The leak is not huge but enough gas is leaking out to kill a small area grass (diameter of a softball) underneath the car over a period of a few days. Also, there are 2 lines that run along the frame below the fuel line. What are these lines? The line that is on the very bottom seems to be corroded in the same spot as the fuel leak.
How hard is it to replace these lines? Is it a simple swap or are there other preparations that need to be made in order to do it. Also, do you have to prime the new line to get the air out of it before hooking it up to the fuel pump or does this not matter? Where can I find replacements for the fuel line and the other two lines underneath it? Also, how much do they cost?
Thank you for your help.
