Cannot fill DEF
Just got back from a 2500 mile trip and the 800 mile DEF warning came on. Went to a DEF pump but it just filled the neck. Went to another DEF pump, same . Went home and used a Ford DEF jug with the Ford spout. It still will not go in. If I squeeze the jug, I can hear a little bit dropping into the tank.
The vent and fill pipes are not kinked. The vent hole in the fill tube looks clear.
I washed off the top of the tank since there is a vent there.
Still no fill. I do not have a bore scope to look in the fill tube. I ran a 1/2 inch flexible hose down the fill tube until it stopped. Still no fill.
Suggestions?
