Gas fill issue

[martha3065]

Anyone have issues getting your truck to accept gas? Last week, I tried filling up and it spit gas back out the vent hole and filler neck. Pulled pump out and filler neck was totally full. Truck was at half tank before I started filling and wouldn't take any gas in. Tried a different station the next day with same result.

 

Dropped off at dealer and they were not able to find any issue. They put 5 gallons in just fine. Dealer couldn't recreate, and no TSBs, so did nothing. I picked it up and filled it just fine.

 

Last night I tried to fill again. Again at half tank. Same issue. Tried another station this morning. Same issue. Tried a third station this afternoon and it initially spit back out. I pulled pump out, tried again, and it started filling.

 

Anyone had this issue?

Search on youtube.com under "gas fill problems" Usually it is the vent control solenoid that is at fault.

Maybe something here.

I've had issues with some pumps in cold weather on previous vehicles. It generally helped to pull the pump out as much as possible so its not all the way in but not far enough out where it would fall out without holding it.

Towed across the country (and obviously filled at many different stations) and haven't had any problems.

I believe it's a GM issue with the way the neck goes to the tank. I have the most issues at pumps with worn out nozzles. The station by my house I have to hold the nozzle while I pump because the nozzle is worn down and the slightest back flow will set it off. I have seen others with GM trucks or SUVs have the same issue. Stations with new nozzles that aren't worn out I can just put it in, latch it down and let it pump. Older nozzles i have to find a happy medium to let the pump flow on its own.

 

Keep in mind I have had no issues at the pump by my house with the wife's jeep or my dodge I used to own. But with my Silverado it can get frustrating. Had a lady in a new Tahoe throwing a fit because the pump kept shutting off on her. I showed her to barely set the nozzle in and let it flow at a slow rate. Any faster of a flow or putting the nozzle in deeper will kick the pump off.

I've never had an issue until the station I use put in all new tanks and a brand new type of pumps. Can't go all in with full lock. I hate it when that happens!

Filled 3-4 times at my normal station. It's only 2 years old and hasn't gotten new equipment since I got the truck. Just the last 2 fills have been an issue.

 

I tried going deep, shallow, fast, slow...any variation I could. Couldn't get her to take it like she should. [emoji12]

 

Dealer advised I make sure I had it all the way in and start out slow. Then ease into full flow. Also said the new trucks have issues if you let them get extremely low, which it wasn't.

 

If it continues to be an issue and a resolution is found, I'll post back here.

I've had this issue with many brands of vehicle. My current truck hasn't had this problem. It's not a GM problem. I had a beater Kia that constantly did it. It's a tank venting restriction, sometimes combined with overly sensitive gas station fuel pump nozzles.

Dealer ended up replacing the tank per bulletin 16-NA-100. Indication was an anti-siphon valve was the cause. No issues in the 5 or so fills since. I was having the issue with every fill prior to the new tank.

Also if ground is not flat at pump, be sure to have drivers side of vehicle higher than passenger side

I typically fill my tank at around half full but my last two tanks got down to the low fuel warning. I've never noticed the issue before but these last two fill ups were frustrating. The pump kept kicking off at the lowest setting. I ended up having to hold it.

This happens 99% of the time when I gas up. Frustrating as heck. Used to do this periodically with my mustang and I'd have to turn the nozzle upside down just to get any gas at all. With this truck I just have to play with it til it will accept fuel and always have to hold it. Sucks.

Every time I pump gas in my 2015 Sierra long bed (34 Gallon Tank Std) is a workout. The handle will not stay locked and will shut off by itself. The only way to get it to accept gas is to stand there holding the trigger at halfway and stand very still for about five full minutes. Also the body panel metal around the filler neck is so thin it flexes if you let go of the handle. Vapor recovery hoses in CA are pretty sensitive anyway but this is ridiculous. This happens at every station I've used--even in Nevada.

 

It's the one thing I truly hate about this truck.

I have the same problem with my 16 crew cab. I am on my second tank and still have the problem. Dealer says to hold handle at a 90 degree angle to fill
