Sinister Diesel Fuel Cap for 2008-2020 Ford Powerstroke (Blue)

This new Sinister Diesel Oil Fill Cap functions like a factory cap, but features custom Sinister Diesel looks. It is made from CNC machined, solid billet T6-6061 aluminum

• Billet Aluminum Construction – CNC-machined from a single solid aluminum billet for superior strength that won’t crack under pressure.
• Prevents Air Ingress & Fuel Leaks – Eliminates the risk of air entering the fuel system and stops dangerous fuel leaks for reliable starts and safe operation.
• Direct OE Replacement – Installs in seconds on factory filter housings using the included O-ring for a perfect, leak-proof seal.
• Heat & Chemical Resistant – Durable aluminum withstands high under-hood temperatures and exposure to diesel and additives far better than plastic caps.
• Quick, Maintenance-Free Upgrade – Simple bolt-on swap using basic hand tools delivers immediate, long-lasting performance.
