2004 Blazer Fuel Line Set S Series 4Dr 2WD & 4WD exc. ZR2 Model 

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: There is a small section of nylon line included which is attached to the vapor line. It is only a section of nylon that will splice to the original nylon line on the vehicle.

Nylon Lines: We do not produce pre-formed nylon lines and they are not included with your fuel lines. However, repair kits are available which will attach to your existing nylon lines providing new connectors for the fuel supply and return lines. The original connections are often seized and damaged during install.

Repair Kit (Connection at Fuel Lines): This is usually required as the original fuel lines are being disconnected from the nylon during install.
