Dealing with a rusty or leaking fuel filler neck on your Chevy or GMC? It's a total pain, but this Dorman replacement is here to fix it without the dealership price tag. This part (number 577-809) is made to be a direct swap for the original one on a bunch of specific GM trucks and SUVs – definitely use the fitment tool on the page to double-check it works for your exact year and model! Dorman designs these to be even better than the original in some cases. This one's built with corrosion-resistant materials to hopefully last longer than the one you're replacing. It meets all the necessary emissions and safety standards, so you can pass inspection with no worries. Comes from a brand that's been making repair parts forever, and they test this stuff so you can trust it. Installation's pretty straightforward if you're handy, but as always, if you're not sure, get a pro to help. Save some cash and get your truck filling up properly again.
