Fuel pump assembly part help!

[DSM Chase]

Was putting a 255 in my dd, the simple Philips head screw that holds the pump on the assembly was tightened to over 9000 ft lbs apparently, it stripped so I cut it off. The ziz wheel hit this plastic part and cut it deep enough to put a small slit in it. Is this just for the fuel return? Does it matter or can run this cut one?

If it matters, were can I get one, part number??

Did it go into where that white pipe is on the assembly? As long as it doesnt interfere with any of the inlet outlet pipes....it shouldnt affect anything.
