Just brought this Mercedes GLC220d 2016 OM651 2.1 diesel and few days later had a massive diesel leak. After investigating it’s coming from this small drain pipe (what I think it is), I replaced the pipe and tied it with wire temporarily and issue is fixed. I’m going to replace the filter. Fuel was shooting out of here when on ignition and running.

My question is, should fuel even be coming through this small pipe with that much pressure, is it normal? I’m a bit worried.
