Are you looking for 2004 Park Avenue fuel lines? We have what you need!

Fuel Line Set 04 Buick Park Avenue 3.8L (K) Non 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.

Quick to house and easy

"Quick to house and easy to install."

— Daniel L. (5/5)

Highly Recommended!!! The gas lines

"Highly Recommended!!! The gas lines that we purchased arrived in a timely manner and they fit great. They were a little longer than the original lines but it wasn't an issue at all. We will definitely be ordering again for future repairs!"

— Halmar R. (5/5)

They will fit a Park Ave ULTRA with a Supercharged Engine with MODIFICATION!!

"Being determined to find a SS fuel line set for my pristine 2004 Buick Park Ave Ultra with the Supercharged 3.8L V6. I took a chance and found this Lines-To-Go set a perfect fit from the fuel tank all the way up to the firewall and back of the engine. Once in the engine bay, I found the provided 3/8" fuel line hose and the 5/16" return line hose to have the right angle connectors that wouldn't fit properly to the fuel ports and that the 5/16" hose was too long. What did work was cutting off the right angle quick connects at the 21" length on both hoses and installing straight 3/8" and 5/16" quick connects in their place. The vapor return line was a perfect fit as delivered. If your Buick Park Ave Ultra VIN number has a "1" for the 8th digit, this modification of the engine compartment fuel line hoses will make this set of fuel lines work with your ULTRA and the Supercharged 3.8L V6. Hopefully, Line-To-Go will introduce this modification to the engine compartment hoses to accommodate all of those of you out there who need new fuel lines and appreciate the ride and comfort of their Park Ave Ultra's like I do. Thanks Lines-To-Go for the great deal and the support. Good luck with your future sales."
