Bring authentic vintage racing style to your build with the Retno Le Mans Monza Flip-Top Fuel Cap. Inspired by the iconic fuel caps found on legendary endurance racers, Can-Am cars, and classic sports cars, this premium multi-piece fuel cap delivers a period-correct appearance, exceptional craftsmanship, and modern reliability.

Unlike inexpensive die-cast reproductions, every Retno fuel cap is sand cast from premium 356-T6 aluminum, just like the original race-proven designs. Each cap is carefully hand-assembled in Georgia, USA, ensuring outstanding quality, precision, and long-lasting performance.

Designed to complement everything from vintage race cars to custom street builds, this fuel filler cap is the perfect finishing touch for Lola T70, Can-Am race cars, vintage racing cars, Cobra replicas, GT40s, Mustangs, Corvettes, Ferraris, hot rods, rat rods, custom street rods, boats, and countless other custom applications.

One of the standout features of the Retno design is its integrated safety wire provision, allowing the cap to be safety wired or secured with a zip tie to the locking lever. This race-inspired feature helps meet the requirements of many vintage racing organizations while adding an authentic motorsports detail.

Available in both vented and non-vented configurations, every fuel cap is fully rebuildable and includes all necessary mounting hardware and gaskets for installation.
