Hi
Can you see the pipe?

It could have become 'kinked' and hence pass little or no air.

Hi - own a 1993 27' sundancer and have noticed that my fuel vent system is
clogged and not functioning properly. Not sure why or how it got there,
but I am looking for a practical way to free up the line. Because the fuel
tank is not properly venting when it is being filled results in a slow
fill and more likelihood of spillage due to overflow. Any ideas would be
greatly appreciated. Thx...
