Complaint Review: J Mac Radiator

We hava an after market oversized gas tank on our diesel truck. It began to leak a year ago. We took it to be repaired at a local shop, who sent it to J Mac Radiator to be repaired. The problem of the leaking gas tank was never repaired, it kept leaking fuel. We took the truck in 4 times within the past year to have the problem fixed, assuming J Mac guarenteed their work. The last time we took it in we were informed J Mac wouldn't stand behind the repair and said they couldn't fix it. I called and spoke with Keith (J Mac), he informed me this was an experiment for a new process, and that they had had other tanks with the same problem, I was then told there wasn't anythikng they could do for us, they couldn't fix the tank and we would have to purchase a new one. If we were informed that this leak wasn't repairable , we would have purchased a new tank in the beginning, now we are out over $1100. and have to purchase a new tank.
