Cured my fuel tank problems on farm tractor. Cut the original plastic fitting off the tank, drilled hole slightly under 3/8, used the strainer to cut new threads in plastic. Cured my fuel flow problems 100%

Great product. Used in my dump truck saddle tank for diesel. High quality strainer for all equipment that use a pipe thread fitting. Great price!.

Works great except the internal threads needed a little work from a pipe thread tap.
