I just took the gas tank to install a sway bar and of course was going to replace the fuel lines that exit the tank and hopefully solve the problem I've had with gas fumes entering the inside of the car. All of the fuel lines that exit the gas tank are plain rubber 50psi max lines and NOT the ones that have braided fabric on the outside. While they look fine, I'm replacing them anyway.
However, less than 2 years ago I replaced the line that runs between the fuel filter and the fuel pump. It's a made in germany fuel line that has the braided material on the outside. It also REAKS of gas as if it's seaping through the hose. The fuel line is less than 2 years old. What's the difference between the braided covered lines and non/braided lines? They both look to have the same thickness of rubber, is one just more heat resistant?
