This past weekend I replaced the fuel feed line on my 09 LNF with a braided line kit from OTTP. This job made me realize how much rust has built up in the back of the car. The areas that seem most affected are underneath the side skirts and the rear corners next to the rear tires.
Thanks!

 

How much rust we talking? Post up a pic to see the damage. And the rockers and rear driver side of these cars are known to rust due to the shielding GM put around the oem fuel lines. I went through the same issue last summer and replaced all my fuel lines including evap lines and did the OTTP Fuel line kit as well. Its a great upgrade and very high quality braided steel line. I also got their stainless braided brake line kit and doing that job over the spring time.

 

Not much rust at all, Ill throw some pics on here later. What car and engine do you have? Just wondering how you routed the fuel line over the exhaust in back.
