Fueling my Silverado

I sure hope somebody will be able to help me. My 2004 Silverado does not want to accept gas. My fill-ups for the last two weeks take 20 minutes each to fill the tank. The nozzle has to be just barely squeezed, so the gas flows in super slow. There do not appear to be any kinks in the fill hose, but I'm at a loss.

PLEASE give some ideas. Thanks

Some GM (maybe all) have a ball in the fill tube used as a check valve to prevent leakage in case of a rollover. That could be "stuck" and causing the blockage.

If you're a "top-offer", you may have inadvertantly overfilled the expansion tank that's part of the emission control system. I recently read a post somewhere (probably here) about someone having troubles with a check engine light, and the code is for that. It's kind of pricy to fix (GM put out a TSB about it), but sounds like it's a common issue.

Yep, was here. Same Original poster....

JohnB is on a distinguished road

I had a 2003 Suburban that did maybe something maybe similar. Wife could really let me know about it too. What I did was pulled the fill nozzle back a little to allow the black vinyl splash guard on the nozzle to not seal off s tight. If I nursed a ¼ full tank just a little like this, the cool gas would seem to break up the tank fumes and allow it to fill. However I could only put it on the first slowest fill click on the handle. But it filled.

In the winter the problem was not as bad. But come late spring thru summer it was back to the above or no go.

If you have one of those positive seal off fill nozzles due to local requirements, …. That is going to be a tough one.

Hope this helps

Don't overfill

Just to second Mooney's post... I was unaware of what the problem is, but when we bought our new 05 Accord the salesman must have told me 5 times during the pre-delivery never to top off the tank. So I suspect this is a widespread problem across brands. Since we bought the Honda I've never topped the truck off either. I usually go to pay at the pump and pay with a credit card so the number of pennies on the tab is completely irrelevant. Topping off comes from the old days when pump jockeys wanted a round number and didn't have to go back inside to make change.

I saw something on a TV program, about pumping gas/topping off, maybe motor week.

That one should click the nozzle on, I thought the high pumping setting, let the tank fill, and when it clicks off, that's it.

I just did that this morning, too bad the program didn't tell you how to pay the $50 and some change, for a little over a 1/2 tank of gas.

Happy Camping !!!!
