No, the tank sat for a long time and got some rust in it. I run through a screen pre filter, then the Fuel pump, then to a Large paper filter by the fuel rails. I would clean it out, but I'd rather just put the LS tank in and call it a day.
I ran the Z for 6 months with the original engine in it and never plugged up the filter. As Soon as I hooked up the LS1 I started getting rust plugged filters. Maybe the violent burnouts shook some rust loose.
Anyway, The gas is clean past the filter so I just check it from time to time and replace it when I see the fuel pressure go below 55.
