[Lusk]

I have been experiencing a bug/water problem in my fuel tank. To late I started using a biocide. Now I have dead bugs in my tank which continually fill the bowl in my Racor unit. The access into the fuel tank is only about the size of a silver dollar. I know I can have my tank cleaned and the fuel filtered but this requires that a larger access be installed. I do not want to go to this expense unless it is the only option.

What I want to know is if anyone knows of a way that I can get my tank reasonably clean with the existing small access hole?
