Blows back fuel when filling up. Have to fill it SUPER slow or in short bursts. Very frustrating. Thanks.
Truck is super slow to fuel up? Do you know of any known problems or fixes? on 2009 GMC Sierra 2500 HD

There's a 8 page document from GM on this problem. What i find very interesting is that it's not a TSB. Contact me at firstname.lastname@example.org
ck for vents or crimped hose going in tank
Thanks for your replies. Will post the findings.
