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.

If you're running low pressure fuel lines, just use fuel hose. I'm not sure about where you are, but parts stores here charge about 3x the price for tranny cooler lines compared to fuel hose. If you're running high pressure lines, use fuel injection hose. The right part for the right job.

I wasn't thinking about buying them to use. I am around a lot of cars like that which get parted out. The one that made me think of this looked just like one I made for a plow jeep recently and it would have reduced the hose clamp connections. That just got me thinking of my truck over in the other bay and whether or not something like that might be an upgrade to a rig like that.

I wouldn't do it, that car is about to be 10 years old. I do not know if transmission cooler line is meant for gasoline/alcohol, that's a whole different ball game as far as material durability. In any case, I'd rather have some new low pressure fuel line than 10 year old transmission line.

If you want a high strength/pressure fuel line that is compatible with modern alcohol blend gasoline, then go for Gates Barricade line. The carburetor version of the line is good to 50 PSI and is only about $2 a foot.

This is what I meant by my question.

I don't need the fuel lines, my truck is already plumbed. I just was curious about the compatibility with gasoline.
