I have the ATS twin fuelers on my truck. I had issues with keeping the belt on it but got that figured out, ATS sent me all new brackets. Anyhow, all of a sudden I have developed a bad fuel leak under hard throttle or at shut off. The fuel is spraying out between the fitting and the rail pressure sensor on the top pump. Everything is torqued correctly and I have already replaced the sensor. Anyone else having this issue??

I have seen a couple leak there. One had a single piece of dirt (or something) on the mating surface between the sensor and the machined adapter. I have also seen one of the adapters that had some rough machine work where the sensor seats and caused a pretty bad leak under pressure. I would remove the sensor and check the mating surfaces.
