Hello! I’m trying to find help with a problem: On my 2011 c2500 gas fishes out after filling. It was having a problem with slow filling, station pump clicking every time I tried to put gas, so I had the main tank, vent valve, and canister replaced. Still don’t know what’s causing the fuel regurgitation.

The fuel pump had been recently replaced beforehand because the sending unit was bad, the fuel gauge was incorrect.

Thanks for reading!
