npub10d2n8qh6ceuylytuwre9vhmkvmghap2nwc36q60whfkjwxaufyxqef5hge (npub10d2…5hge) that’s what the return line is for in a common rail diesel or DI gasoline engine, but traditional diesels have injectors that are always open, so I was thinking there would be no circulating fuel. Apparently it’s for an accidental overpressure / oversupply situation, to avoid a back pressure spike which would damage the (pump) pistons over time.
