I’m having a weird issue with my 2013 Silverado. It has a 5.3. When I’m fueling the gas pump constantly shuts off unless I hold the nozzle at just the right position. It can take 5-10 minutes to fill at times. I read on this website that the issue could be my vent solenoid so I replaced that with the ac delco kit with all tubes included. I didn’t reroute the filter though. I’m wondering if there’s another vent to let fumes out of the tank so the filler neck isn’t backing up. A local mechanic claims that some pumps do that but I’ve gone to this gas station for years and it never did that before. Any ideas?
