I bought a section at 48". Cut the flares off and lose the b-nuts. I used a manual tubing bender I borrowed from work. Makes quick work of the bends. While your at Napa pick up a foot of 5/16" hose for the connectors. I had some left over spring clamps from the hoses I deleted under the plenum so I used those to secure the pipes. The run on the left side is kinda long so you'll need some type of clamp to secure the pipe against vibration. The pipe on the right is short and doesn't require a stand-off.
