Filling Tank with Fuel

[kmc58]

GMC70 has a point. As the fast stream of fuel enters the tank, the same volume of air is displaced and has to come out. Many fuel tanks are delivered with 3/8" or 1/2" breather hose, that will not keep up to expel the same volume of air. So the air is trying to come out the fill tube, and triggers the nozzle cut off.

Yes, our thoughts too! Thank you!

What would cause a problem with filling our Thor Aria Motorhome with diesel
The pump keeps clicking off
Takes forever to pump fuel

Thanks!

Good evening I am not sure if you have solved your problem . I have a thor aria also ,I have a fill cap on both sides of my coach when I fill up I loosen the cap on the other side of the coach this allows the pressure to release and it fills quite quickly . Just make sure you close both caps after filling. I hope this helps.
