Rugged Ridge 3 Inch Body Lift, 97-06 Jeep Wrangler (TJ) - Manual (Page 7)

Step 11: Install fuel extension pipe
Note: several sizes have been supplied. Use the correct one for your application. With
fuel line cut the tube should fit snug inside of rubber fuel hose.
On later model Jeeps equipped with on-board vapor recovery it is important to not
cut these lines. These lines have been supplied from the factory with extra length.
Just pull enough vapor lines loose as needed for lift. “Do Not Cut Vapor Lines”.
