Installation was easy. Some tips: Hose location and configuration just like in the photo of the product (If trying to assemble in a stock config). Top-left of the photo is front of vehicle. The barbed SS hoses come up and over the plenum but under the balance tube. Some manipulation of the dampener pip makes it a bit easier to get to work. Install the connecting hose before install of the rails. 5/16 hose came with 1/4 barbs on the lines. This made no sense as the image is 5/16 barbs.
