Correct fuel line material from tank, or "so that's where the gas smell is coming from" Options

[rjames]

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? (IMG:style_emoticons/default/confused24.gif)

Sounds to me the connection at one end- either to the filter or the pump- is seeping. Fuel then is wicking up the braid. On my '76, one end got hard and wouldn't seal any more, but yours are fairly new so that's not likely.

I'm sure that the hoses that were replaced by the recall are high pressure. They have a thicker wall than the braided ones they replaced, and so are fatter- 13mm OD vs. 12mm OD- and are quite pricey. The original 12mm clamps don't fit unless you try real hard and distort them in the process.

I would do the engine compartment. Porsche spent a lot of money on that recall, so they must have thought it necessary.

The only hose under the tank that is high pressure is the one that runs from the pump to the tunnel connection.
