how did you end up finding it mate? And what was the solution, a new line?
Iirc I did the bottle method injector leak test and happened to notice bubbles from the return line. The hole was right down the back of the engine near where it goes through the tunnel, I couldn’t see it but my hand came out with diesel on it.
Replaced the line and spliced it into the old one with some rubber fuel line because I cba to drop the tank.
