1st Gen CX9 - Fuel Filler Neck

[sarpworks]

Hello everybody,

I think I am having an issue with fuel filler neck on 2011 cx9 gt.

I found some wet spot on left hand side of the tank( gas filler side). The drive way is slope and it happened only with full of tank. does anybody have any instruction how to replace fuel filler neck?

Loose fuel filler neck - anyone else have this issue?

I have a 2016.5 GT, 2.5 months old. I've noticed the fuel filler neck is slightly loose/wiggly when I fuel up/ insert the fuel nozzle. Seems a bit 'flimsy'. By comparison, none of my other cars' filler necks moved at all. Is this normal with newer/modern cars? Or should I have this checked...

Or this one... Gas cap / Fuel Filler Cap Issue

I checked this Mazda parts site and perhaps the diagrams could help..?

I've gone as far as removing the fuel door release, but didn't pay attention to the filler. Should be clamped at both ends, so will have to gain access from inside to do or see anything for the upper part.

Best to get under the vehicle to see where it is leaking from; could be the filler, could be the sender, could be a hole in the tank, or could be any of the multiple hose connections on top of the tank.
