It will always drop to 0 psi eventually. What period of time are you talking about? Within a second or two? Five minutes? Ten?
Not trying to be a smartazz, just need some clarification.
Also, assuming it is a WS6, what year? Any mods? A signature would be nice...

Could be the pump that you installed or the connection between it & the fuel bucket.
