Exclamation Fuel line questions

My truck has a rubber fuel line from the pump to the carb, I plan on putting a hard line on it real soon. My question is, can you use a copper line to run or does it need to be steel? The reason I ask is, I have access to the copper tubing, and I love the look of it too. If it's not a good idea I'd like to know now before I put it on in the next few days. And if it is ok, what would you recommend I use for the size. I'm thinking 3/8" but I'm not sure. Thanks ahead of time.

Re: Fuel line questions

Dont do it. Copper will fatigue and break over time due to vibration. Stick with steel.
