Intended for compatible 1973 Chevrolet Chevelle applications. Confirm body style before ordering. Verify fuel-tank design and filler opening location. Confirm filler-neck routing and bend shape. Check outside diameter against the filler hose. Verify fuel-cap style and sealing surface. Confirm mounting flange or bracket configuration. Vent routing may differ depending on emissions equipment. Aftermarket fuel tanks may use different filler-neck dimensions. Modified trunks, custom tanks, or fuel-cell conversions can affect fitment. Do not assume filler hose, cap, clamps, seals, or mounting hardware are included. Compare the original neck’s length, bends, mounting points, and hose connection before installation.
