Are you looking for 2003 Park Avenue Ultra fuel lines? We have what you need!

Fuel Line Set 03 Buick Park Avenue Ultra 3.8L Eighth VIN Digit (1) Supercharged

Please Note: Before installing your fuel line, a shipping bend will need to be removed from the lines labeled RL251B313A2, SL251B375A2, and VL251B313A2. See the video below on how to remove the shipping bend.

Nylon Line Attached to Vapor Line

The nylon line attached to the new vapor line is not a direct replacement. It is only a section of nylon line that will splice to the original nylon line on the vehicle.

On the opposite end of the original nylon line, there are connectors. These connectors may be damaged during removal. If so, we offer repair kits with new OEM connectors. These will, also, need to be spliced onto the original nylon line.
