Gas pump always shuts off early

[tahoe4life]

Wife just bought 2010 Tahoe LT and every time she stops to fill up, the pump shuts off before it's full. I thought it was a fluke or something she did to cause it but it kept happening then it happened to me. Tried putting nozzle in different depths still same outcome. This happen to anyone else? Seems weird to me...

Its the vapor recovery system telling the pump, the tanks almost full..
This prevents spills.


Its normal.

How full are you able to get it? Ive heard of this happening if the vent solenoid is stuck closed.

Mostly shuts off at half tank, sometimes quarter full other times three quarters full. I've never experienced this with any vehicle before.

Of course it's normal - if it shuts off just before it over flows. I'll give you the benefit of the doubt that I wasn't clear enough in my explanation and that you're not that big of a smart or dumb arse.

Mine does the same thing. Clicks the pump off every 5-10 seconds. Super frustrating. No idea why.

yea, your question sucked.

This has happened to me on several occasions.
If I put the nozzle in all the way it tends to happen more often.
I end up putting the nozzle in just enough to catch and it pumps fine.

So yeah like I said it most likely is the vent solenoid. It will most likely need to be replaced.

I used to manage a gas station another reason for shutting off is if there is too much demand placed on the pump as some gas stations split the demand of the supply pump between the fill stations. This is found in older gas stations. There is in some but not all gas stations a vapor recovery system this system is designed to prevent gas vapors from escaping into the atmosphere. if you pull into a gas station and find a black rubber fitting over the nozzle this is the vapor recovery system. This can in some circumstances become full or not be functioning properly which will prevent your vehicle from filling properly. Your vehicle also has one which is designed to burn the gas in the engine. This can also malfunction but as a general rule your engine light should come on. Hope this helps

Thanks for info, I'll check into this replacement.

That does help, thanks for the insight, always thought those rubber grommets were splash guards.

I see I was right and didn't need to give you benefit of doubt. I didn't do a 2 second search because I enjoy the conversations with guys on this forum as most share similar experiences, are well informed and very helpful. Maybe you should take notes then go be a smart ass somewhere else.
