Can't keep fuel equal in tanks.

Yeah I'm sure it's possible. Problem I have is being able to properly check them. They are not removable, appear to be welded in the threaded tank port. I used a bore scope to look at the stand pipe while the engine was running, with the fuel level low so most of standpipe was not submersed in fuel. I did not see any fuel leaking around outside of pipe. This was after I removed the pump return from top of the tank. There was no fuel splashing in like there had been. I know it's not a definite test to say they aren't cracked, but I don't know what else to do. I'm not buying new tanks, that I know.
