Just as the title says. Do you guys recommend buying them from GMC, or another source? Also, is it possible to replace them myself?

I get mine from NAPA... I will find the link on how to change them.... Its super easy.... It takes me longer to get off the couch then it does to change it......

i got 3 of the napa filters to my door off EBAY for 45 bucks

there is a do it yourself DIY thread about doing the fuel filter swap


this reminds me...i need to do mine this weekend

Here is the thread on how

Sweet guys, thanks!!

The only thing I do different on my truck is I remove the inner fender well cover to change it. Its a lot easier....
