Not the tank necessarily, but the pump would be in question. When you had the filter off, did you try cycling the pump to see how well fuel was shooting out? That's one of the things the TBI system is lacking, a schrader valve to make it easy to check your fuel pressure.

It's quite possible the pump is working ok initially, but after running a short while, it starts to die out. I'd want to know for sure before digging into the tank to replace it. Did you check fuel flow with the line up at the TBI disconnected? If fuel flow down by the filter is marginal, it'll show even worse uphill at the engine. If you can, do a comparison; check the flow at the TBI before a cold start, then see how it is after the engine dies. I know this isn't a scientific way to determine just what your actual fuel pressure is, but if it goes from flowing to dribbling, you'll know the problem is at the pump. And remember, use a catch container so you're not squirting gas all over.

Ran a test on the injector connection, it works and has plenty of power. Gonna swap out the injector tomorrow and hopefully my problems will be solved so i can still cruise in the Camaro while Im waiting for the LS1 to get here.
