Hard to pump gas

[rd62rdstr]

2011 yukon denali just started give me a hard time pumping the gas stopping every few seconds. I know it could be a clogged vent but I don't know where it is or how to get to it. I never looked under the truck so not sure what I'm looking at

I have had the same problem with some pumps at gas stations here in California due to their vapor lock systems on the nozzle. I found that other pumps from different gas stations do not cause this and I don’t have the problem in other states where they don’t use the vapor lock nozzles.

Like avalonandl said, Google is your friend and you are likely spot on with the vent problem. Has the tank been dropped recently?

Curious why you ask if the tanks was dropped? I recently had the tank dropped in my 12 Yukon Denali at the dealer to replace the fuel pump module & have been having a hard time filling up since. It is progressively gettin worse. Dealer did a visual inspection & stated "everything" looks like it should.

The reason I asked is because when the tank is dropped and then reinstalled, sometimes the tech will kink or route a hose wrong where it can be pinched during the reassembly process causing vent problems. If the problem did not start till right after the tank drop then I would suspect the problem could be related. I have seen it in shops I ran before, especially when the original shop "took a look at their work" and said they saw no problem. They could also have damaged some of the vent parts back there unknowingly.

My '05 Yukon..... Some gas pumps have a stronger flow..... It has happened to me once in a while.
I slow the gun a bit and the problem pump fills ok....
Maybe try a different station and see if there is a different result.

Engine turned off when re-fueling?
