No, I did not replace the fuel filter on the red one. I just replaced the fuel filter on my blue one a month ago. OBTW, Buster began cranking a little longer than he should about a month ago... but ONLY when the temp dropped in the mornings. No CEL codes either. I changed his fuel filter (he was over-due the change) but it didn't help the cold start so I replaced the idle air control valve with a new one from NAPA. The IACV fixed the hard start but that bugger cost $320 (plus shipping from VA) to replace it. It only took 15 minutes to swap it out - loosen the two bands holding the "L" shaped air hose from the air intake, remove the electrical connector from the IACV (clip), remove two phillips screws to remove the IACV and then reverse procedure to assemble... but OUCH$ that thing was salty priced!$!
Fuel filters are tucked WAY up under the frame on the right rear in front of the fuel tank. A real PITA to access plus the bolt that holds the band around the filter are usually rusted badly and you have to fight the bolt... blindly. Hindsight, it might have helped to pull the right rear wheel, put jack stands under the frame and work from the wheel well. I don't think you could see much better, but it probably would have been a hell of a lot more comfortable while doing it.
