hard to fill gas tank 2016 sierra

Colossus · December 17, 2016

After having had to replace a charcoal canister in a previously owned vehicle as a result of damage to it being caused from topping off, I'll never do that again. $600+ repair. I suggest you avoid topping off to see a round $$$ amount.

I'm having a very similar problem on my 15 Silverado, but I have noticed that using the same pumps, cause the same problem. I'm not having this problem at all pumps, but I have found this problem at various levels, not only below 1/4 tank. When I start experiencing this problem, I pull the nozzle out, reinsert it and try again. Usually, with success within 1-3 tries.

My 2015 has this problem. Since day one my truck has been a royal pain in the ass to fill up. Takes forever and constantly shuts off. I really don't want to change gas stations since the station is just yards away from my house.

It seems that most nozzles nowadays do not have a LOW setting the lock seems to only engage at almost full blast. Here is my CONSPIRACY THEORY this is done on purpose to makes the gas station some extra money. All pumps now have a recovery system and at full or near full flow a good bit of fuel is recovered and never makes it into your gas tank even though your are paying for it. Double wammy you are pissed off about the nozzle cutting off plus buying the same fuel over and over! These guys are BRILLIANT .

Yup, that bottom 1/4 makes the pumps shutoff like crazy. Once I get some gas in it... smooth sailing.

Very good point. I have and old friend who delivered fuel for many years. He got paid by the amount of fuel actually delivered. The despencing stations and pumps meter off the vapor not the actual gallons pumped. Slow fills in cool temperatures net you the most fuel for your money.

Another thing he told me was as I said he got paid for the amount of fuel delivered. So if he had a load of 2500 gallons of 87 octane and the tank only held 2400 gallons the remainder would in up in the 93 octane tank.

The vapor recovery system you are referring to is slowly being decommissioned, and is not required on new builds or when new dispensers are put in. Your theory is true tho some fuel is inadvertently pulled back into the system.

Yeah lol a long time ago they used to do that, but with the ATG and Veeder root systems reporting to corporate it's impossible to get away with. Now the mom and pop places it could happen. Also the underground storage tanks are a constant temp being underground (also monitored by the ATG and Veeder root) so temp has very little to no inpact on fill ups.

If it's less than 7 years old, the charcoal filter should be covered by the government-mandated emissions warranty.

I haven't experienced this issue with my truck yet. I had an 08 Malibu that would constantly kick a BP gas pump off no matter how much fuel was in the tank. Worked fine at all the Kwik Trips in the area.

My local BP is the only pump I still have issues with it. The nozzle has a big rubber "spring" type shroud which if I don't hold it in my tank it pushes the pump nozzle so far out of my tank it shuts off.
