Shop LinesToGo for 2003 GMC Yukon fuel line set - 5.3L (L59) Flex Fuel Only
Location: Engine to Hose Connection off Fuel Tank
Please Note: Original equipment Suburban/Tahoe/Yukon front fuel line sections can be difficult to install from the engine connections down to the frame rail. These LinesToGo 188 Series come with front flexible stainless steel braided Teflon hoses, making a difficult and time consuming job, a whole lot easier and faster. Routing clips and hardware included.
Nylon Lines Between Fuel Lines and Fuel Tank:
Nylon lines between the fuel line and the fuel tank are not included. We do not make the nylon lines for this vehicle. However, you can purchase a nylon repair kit, 3071-01, which will attach to your existing nylon line providing a new connector for the supply and return lines to connect to.
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.
