My 6.5 is running poorly, I thought the turbo was bad but, it still turns freely and appears to work just fine. Another problem that needs attention is the fuel tank. I went out to my truck when I left work, the same day that it started running poorly, black smoke and all, and there was a noticable puddle of fuel beneath the tank. When I removed the fuel cap, there was no familiar air release sound. The leak is consistant but not pouring. The hole is large enough to warrant not driving it, not to mention the poor performance. I'm curious if the two problems are related. Would a large enough hole in the fuel tank cause the poor performance?
