it could possibly be the pump, or regulator. they aren't exactly meant to see pressure as high as what yours was with the clogged return line

Yea I know it. I'm going to try and check a few more things. I want to make sure it is not an electrical things. So I am goingg to check my connection to the DME. Cause the hesitation and misfire, only happen after the DME goes closed loop. (WARM)
