Hello All,

I am planning on replacing some fuel lines this week while I reseal my intake. Only planning on replacing the lines from the fuel rails to the hard lines underneath the car. I just wasn't 100% positive on the adapters I needed for underneath. Will I just need another pair like the ones listed in the link below to adapt to the hard lines going back to the tank??

Nah just go onto GMparts direct and type in the part number, they come with everything just like the original lines.

Same stickers and all lol

 

There are quick connect fittings on both ends of the stock fuel lines. If you want to use braided S/S lines with -AN fittings you will need 2 sets of adapters.

On the other hand the stock line bundle is available fairly cheap from GM.

 

Not to mention braided stainless is a hassle to work with. It does look nice once it's finished though.

Great! Thanks for the help everyone. I am definitely going with the stainless/braided fuel lines. Not afraid to throw down a little bit of cash to dress up that engine bay.

Would any of you guys know the size of the vacuum line that runs by the fuel lines?
