I have '97 Ford E150 5.4L, back in the doghouse engine rear, you see the fuel rail has a plastic rubber tube connected to the other fuel rail side, what is the plastic/rubber tube called?

It's shaped like keyboard symbol [ and about 18-20" long connecting joining the fuel rails to each other, and can this bought at retail stores, or oem part only? can't seem to find at autozone..etc...

 

You need to purchase the entire fuel rail system to get thet part.
