Abstract: An apparatus and method for supporting a contamination detection system for determining the presence and levels of foreign particles and/or water in fluid samples, such as fuel. The apparatus may include a contamination detection system, a hollow rod, and a bypass tube. The contamination detection system may have a flush mode in which the fluid bypasses a detection monitor of the contamination detection system, flowing into the hollow rod. The contamination detection system may also have a test mode in which the fluid passes through the detection monitor, through the bypass tube and then into the hollow rod. The hollow rod may be mounted to a collection container for receiving fluid from the hollow rod. A ground wire for eliminating static build up during contamination testing may be conductively coupled with the hollow rod and may be supported on a ground wire support structure fixed to the collection container.
