Found a solution , lightly sanded outside of tank at cracks , used a product called seal all , spread on and into cracks , pulled a slight vaccumn on tank and let set for a week , here it is mostly in the 90's so it cured very hard . Filled tank with fuel and let it sit for 3 weeks , No leaks , don't know if it will hold under riding conditions , but a new tank from Partzilla , best price found , 255.00 plus frt. Hope it works !
