I have changed my canister, purge valve, still won't take gas, I found a small sensor along the frame inline from 2 evap hoses on tank to canister. this is getting frustrating any help would be greatly appreciated thanks.

 

I've been having the same problem. Every time I go to fill up, the pump will cut off. I have to keep pushing the lever of the gas pump. Very frustrating. It takes about 5 minutes to get 10 gallons of gas. The only thing I have done so far is check the lines on the purge canister valve. I got an air compressor. The line on top is not clogged. (air is shooting out of the holes around the tank)

I can't even find the charcoal canister. I guess it might be underneath.

Any help would be appreciated.
