Hi Michael

Looks Like yours must be a rebuilt Scot, where the injector pipework does pass quite prominently through the running plate just aft of the nameplate. There is quite a tight elbow where it passes through, not ideal for injectors. I have got around a similar problem by using a lost wax cast elbow for a vacuum pipe sold by a company called 17d silver soldering pipe in one side and screwed fitting the other. Had to ask to buy just the 3/16 elbow, but it did come out neatly (this wasn’t for an injector) Can’t photograph it as everything packed up for imminent house move. Alternatively could run injector pipes more directly, perhaps even inside the frames, which would give a much better pipe run. And make the visible pipe on the running board as dummies. The nameplate could hide a multitude of sins and avoid any sharp bends in the injector pipework. Just had a look and EKP supplies sell a little casting of elbows which could be useful, listed under Kennions misc castings.
