Re: fuel filter?
I'm a GM mechanic and have dealt with the fuel filters on the Sonomas pleny of times. It's a pain to get off but you can do it. Just disconnect the couplers and use LOTS of force to get the old filter off, then use a little bit of oil or great and rub it around the new filter to slide it onto the bracket.
P.S. I forgot to mention, the disconnects WILL be a pain to get off because at my dealership we use a J-Tool to get them off, for you I would recommend a bent plier or small screwdriver and lots of cursing to disconnect it.
