Fuel system confusion I'm doing an ls swap in my 92 mustang. I have the corvette fuel filter already and all the lines are plumbed. But, i was just wondering. Dont the stock ls1 returnless fuel rails have a regulator built into them?

NO they do not the Corvette filter/regulator has one built in. The factory rails do NOT. GM calls it a pulse dampener whatever that means...even they realized they don't need it and removed it in later vehicles.
