GL320 return line leak
I've spent the day wrestling.
I removed the back seat and removed the little round cover to expose the top of the tank to search for the diesel leak.
The return line nipple was spewing fuel. We tried th replace the o rings but no dice. Eventually the return line nipple broke off. I suspect it was cracked causing the leak.
Tomorrow im headed to Sun Motors MB dealer to see if I can get two new flexible fuel lines and also the fuel sending unit.

New fuel sending unit, hoses and gaskets ordered. Due in Thursday. Total around $400. I have to open up the passenger side of the tank also to access the pump since the fuel lines from the sending unit go across to the other saddle and hook to the pump.
