Fuel tank part question
 

I dropped my fuel tank to replace the pump(failing). Upon doing so I noticed a fine crack in one of the tank connections. From an extra hose clamp i take it the last owner changed the pump and apparently broke this one because there is some epoxy around it.(I wiggled it and it all broke off)

My big Question is that it doesn't look like the part is removable from the tank. Do i have to replace the whole tank now????
TIA.
