I have a 96 jeep Cherokee 4.0L 4wD. A there’s this I believe fuel return line that Runs from the Evap canister down the driver side behind the fuel filter to the top of the gas tank. The biggest portion being metal and I was curious what the name of this line is call because mine is so rotted out that I can crumble it with my finger tips bought my jeep last year and I’m slowly replacing everything that looks necessary just finished the front end suspension front and rear breaks, shocks.now I’m doing brake/fuel filter and lines then rear suspension.

Not a fuel return line, 96 was the first year for the returnless fuel system. You're looking for the Evap line. I'd grab some appropriate size nickle copper line and just make your own to replace it as I doubt you'll find a OEM line anywhere but from a junkyard.
