Under the Straw Hat – Restorer’s Insight While most associate return line tanks with later C3s, this early tank used in high-performance L68 and L71 builds features a clean non-return configuration and small-side indent pattern. Matching this detail can make or break an NCRS-judged restoration. Always verify your car’s original tank configuration before ordering.
Important Tech Note All fuel tanks are manufactured with a sprayed-on interior rust inhibitor. This lining must be removed before installation to prevent dissolved preservative from clogging your fuel system.
How to Prep Your Fuel Tank for Installation • Close off tank openings with rags and duct tape • Add cleaner (Carb Cleaner, Acetone, or MEK) • Caution: No smoking or open flames nearby • Add small metal parts (nuts, bolts, washers), shake and rotate • Repeat until cleaner drains clear; dispose responsibly • Remove rags, tape, and metal parts—allow to dry completely
Whether you're restoring a tri-power big block or just ensuring leak-free performance, this tank delivers authentic fitment and the kind of precision detailing that turns heads and wins shows.
