Overview:

The Carli Anodized Fuel Cap is a premium upgrade designed specifically for Ram 1500, 2500, and 3500 models from 2011 through 2018 equipped with Diesel Exhaust Fluid (DEF) systems. This fuel cap replaces the factory unit in the DEF fuel filler area, providing enhanced durability and corrosion resistance. Ideal for Ram owners seeking a reliable, long-lasting fuel cap that withstands harsh environments, the Carli fuel cap combines functionality with a sleek anodized finish that complements your truck’s rugged aesthetic.

Whether you drive your Ram for work, off-road adventures, or daily commuting, this fuel cap ensures a secure seal and easy handling, even in cold winter conditions. Its high-strength magnet offers convenient momentary storage, preventing loss or damage while refueling.

Key Features:

Engineered for durability and ease of use, the Carli Anodized Fuel Cap offers several standout features:

• Precision billet anodized aluminum construction for superior corrosion resistance
• High-strength magnet for secure, temporary holding during refueling
• Designed to fit factory fuel filler openings on DEF-equipped Ram trucks
• Easy removal and installation, even in freezing temperatures
• Compatible with a wide range of Ram 1500, 2500, and 3500 trims and model years
• Enhances the appearance of your fuel filler area with a clean, anodized finish
• Built to withstand exposure to road salts, chemicals, and extreme weather

Construction & Design:

The Carli fuel cap is crafted from high-quality billet aluminum, which is then anodized to create a tough, corrosion-resistant surface. This process not only protects the cap from rust and environmental damage but also provides a sleek, matte finish that resists fading and scratching. The robust design ensures the cap maintains a tight seal to prevent contamination and evaporation of DEF fluid, which is critical for maintaining your truck’s emissions system performance.

Attention to detail in machining and finishing guarantees a precise fit and smooth operation. The integrated magnet is strategically placed to hold the cap securely during refueling, reducing the risk of misplacement without interfering with the cap’s sealing function.

Installation & Fitment:

Installation is straightforward and requires no special tools or modifications. The Carli Anodized Fuel Cap is designed to directly replace the factory DEF fuel cap on compatible Ram trucks, fitting perfectly into the existing fuel filler area. Its user-friendly design allows for quick removal and reattachment, even when wearing gloves or in cold weather conditions.
