Tranny line for fuel?

[Zebb]

I was recently pulling a radiator out of an 03 cavalier with an automatic and noticed that the transmission cooler lines looked like something I could have used for a fuel line application a while ago. Has anybody ever heard of using that type of line for fuel? If regular fuel line is not recommended for transmission coolers would that make the transmission lines more than suitable for low pressure fuel lines?

I was thinking that something like that would be just right on our squares where we have steel to rubber to steel connections. Like on mine I run an electric fuel pump in line.
