Does it affect how your car runs? If not it should be ok...why'd you replace brand new fuel line w/ more brand new fuel line lol?!?

after it has fuel. like when its running i can see bubbles in the line.

Your fuel line is getting to hot. it is causing the fuel to evaporate in the line. Re-route the line away from the engine as much as possible. Also, anywhere that the line is close to the engine, put some heat shield tube over it.

Hope this helps.

check the tank cap o-ring. make sure theres no cracks or tears...usually thats the problem. and zip-tie all the fuel lines to the tank nipple and all that...

Oops, he's right. I forgot to mention that stuff. try what he said first, then if that doesn't fix it, do what I said. That will get you fixed up for sure.
