Hi there, after a mechanic worked on my B1750 engine I have a diesel leak from the middle injector. Leak is at the arrow in the photo. Compression washers are new and no sign of leak at injector rail
. Diesel slowly seeps at connection at the arrow after a few minutes running. All connections are good and tight. What do I need to do to fix this? (Mechanic who worked on the engine no longer available, so will need to fix it myself). Thanks, Treadman
