Are you looking for 2003 DeVille fuel lines? We have what you need!

Fuel Line Set 03 Cadillac DeVille 4.6L engine w/ the 4th and 5th VIN digits KD, KE or KF

Retainer Clips Included On Lines: The retainer clips provided on the replacement lines may not be needed. The replacement lines will plug into connectors which have retainer clips inside them.

Sometimes during removal of the OEM lines, the retainer clips inside the connectors may be damaged. If this is the case, you will need to leave the retainer clips on the replacement lines.

If the retainer clips remain inside the connector undamaged during removal of the OEM lines, you will not require the retainer clips provided on the replacement lines. The retainer clips will need to be removed before plugging into the connector. 

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.
