Yea I wasn't too concerned about the filter, just curious what the startup cause could be. Like people have said, it could just be the switch to summer blend.. higher E85 content in the fuel plus all that stuff about fuel pressure/vapor/cranking enrichment, I'm sure that's a contributing factor.
The fuel filter degradation sounds like an isolated incident on a specific tracked car in very specific conditions. My car runs better than ever on E85 so no way I'm shying away from it now.
