Hi gents for some time now I've had a problem with slow response when pulling out from stop when tank is half to fourth remaining. I've run purge thru it changed prefilters, main filter to no avail. Last weekend I went up to Beufort, SC and it ran great above half full but after stopping at rest stop above Daytona it started. I went to next rest stop about 50 or 55 tops. Luckily nobody knocked me off the road,ha,ha. what do you all think?? screen in tank? fuel is clear and clean in filter Thanks for any and all help bubbaz2
