You need to split one 15mm line into two and the metal tee you grabbed off the shelf is already showing rust at the threads. This Jaycar 15mm tee is glass reinforced nylon composite. It won't corrode, won't electrolyse, and it doesn't care about the diesel splash or the UV baking it all summer. Rated from -20°C to +110°C. Pop two hose clamps on each port, tighten, and walk away. One less thing leaking under the bonnet
