If the leak only occurres when the system is pressurized then it is most likely not the tank. the FW pump draws from the tank and pressurized the system/lines so the tank is not pressurized at all. I've heard of owners sprinkling baking soda around the bilges. Leaking water will leave a trail through the soda and hopefully help Point to the source. There are also florescent dyes available at auto parts stores (some are visible with special glasses). Mix the dye into the tank, pressurize system for a while then look for the marked trail in the bilges . Good luck
