leaky feul line at the tank pump

[jsthnt@gmail.com]

I was haveing power issues, so I dropped the tank cleanned the rust out. Then I got problems. I found out that the fuse for the pump was bad. When I replaced that I found out that the line was leaking where it conected to the pump. I had someone else look at it and they thought it was cross threaded. So they tapped it and it still leaks. I then replaced the whole line (it was getting to short and had a kink in it any way). And it still leaks.
So what do I do?

Thanks
