This isn't a 3L specific part but should be changed when pulling the engine because it's so hard to get to. It's a fuel vapor hose and it runs from the UIM to it's connector on the firewall. It becomes very brittle over time as I've found out. It's about $20 from Bill J. It's a ribbed plastic tube and locks into one of the 2 ports on the FW. Part number is F6RZ-9K313-BC. Bill Jenkins had took a while to find this so I thought this would help.
