A cushioned P clamp with a 12.7mm inside diameter, matched to AN6 hose. AN6 is the default size for fuel supply and return on a great many builds, which makes this one of the most useful clamps to have in quantity. The cushion inside the metal band holds the hose securely while protecting the braid or cover from abrasion and damping the vibration that would otherwise work the fittings loose over time. Space clamps evenly along a run, add one either side of any direction change, and anchor them to solid structure. Size from the hose outside diameter, since fittings and covers vary between hose types.
