2002 blazer. When I pump gas it cuts off about every 30 cent I pump. Had this issue for a while now. Saw a video Scotty Kilmer uploaded where he blew out a hose on the evap solenoid to fix it, but can’t locate it and not even sure if that’s the problem. Any help would be greatly appreciated.

Thanks

 

It should be behind the drivers side rear wheel, behind the side plastic piece. It's a black box.

Could be that or vents on the tank, or something else.

On my wife's sonoma, it was the carbon canister, and also a valve on the inside of the fillers neck that would get stuck.

 

There are two ways that filling up can be slow, on the fill side or on the vent side. On the fill side there can be an obstruction in the fill neck to the tank including any check/anti roll over valve. I’ve seen pictures of a swollen check ball.

Then the tank has to be able to vent the displaced air as the tank fills. First is any roll over valve at the top of the tank, the vent hose to the canister, the canister, the vent hose to the vent valve, the vent valve and any hose after the vent valve. The two most common problems are a failed vent valve which is not normally open as it should be. The other is a plugged charcoal canister. The simplist way to figure it out is to start disconnecting hoses on the vent side and see if that does the trick. Lastly, it can be the hoses themselves which can be plugged with bugs or dirt.
