Top swap with a gen V, rockers, and headers here. Running 60s with a rewire and I love me some e85. Also loving nice cheap gas. Never had to change my fuel filter because I have exactly 0 sediment in my fuel system. Last time I had to sending unit out everything was squeaky clean. Adecker still has his stocker in if I remember right. If your car has been taken care of you shouldent have to worry about filters.
