| I'm curious if your reason is correct or not.   Isn't it fairly common knowledge that you can use a freezer to  loosen a difficult bolt stuck in a part?  How would this be any  different with the fuel rail?  Why wouldn't it seal more, as it  heated up?  I honestly do not know the answer.  Can you recall if the fittings (AN-8 Unions) were loose when  you went in to retighten them?
