The 2 have had a long relationship and therefore I question the "recomended status". I wrote to Standyne and asked some questions. The answers were pure marketing BS. BTW, Standyne has nothing in the product to deal with water. Seems to me others concentrate on handling water in the fuel and Standyne just ignores it.
