My 2007 Weekend Warrior Pump Station 40 gal Gas Tank has sprung a leak. It seems to have corroded or small pinhole (not at the seam, it is in about the middle on bottom of tank). Just called Warrior Lifestyles for a replacement, and nearly fell over. They want $650, plus my trailer would have to be retrofit for the new style tank. Can the tank be fixed?? or do I need a new tank? Has anyone had to do this?
