Hello,

I have a similar but different diesel leak on the same line and spoke with Newell about it.  My leak is also on the green tubing that is the fuel return line, but the leak is occurring at the push lock fitting on the diesel tank.  It is conveniently located in the middle of the coach in the front passenger side of the coach.  Seems there is not enough pressure in the return line for the push lock to seal properly.

Newell indicated the fix would be to empty the tank, lower it enough to gain access to pull the original fitting which has a short dip tube, replace the fitting with a compression fitting, lift the tank back up and then refill it.  

Ours was found as we smelled diesel in the bedroom after a downhill and seeing the bottom of the coach, this was not the first time as I can see diesel stains on the insulation below.

If anyone has any other ideas how to remedy, happy to hear them!  The photo makes it look like there is room to get in there...ah, maybe not

BTW, Swagelok makes very good compression fittings, but a bit $$$.
