Can anyone confirm the diameter of the 4th Gen fuel feed hardline? I'm hoping it's 5/16". I plan on running an inline fuel filter and converting a portion of the line to stainless steel braided.

Also, any information about the return line diameter is equally appreciated. Thanks!

 

It's kinda ghetto, but I had to cut my fuel line and I used a rubber line with 2 hose clamps and it has not leaked for almost 3 years now.

 

if your trying to push alot of hp and need a good amount of fuel i know fastturbo has a full stainless line kit from the tank to your fuel rail.
