Standard Ignition SK146 Fuel Injector Seal Kit

Fuel Injector Seal Kit for Ram and Dodge Ram

Standard Ignition SK146 is a fuel injector seal kit built for sealing the injector-to-fuel rail interface on select Ram and Dodge Ram applications. It uses high-temperature Viton(R) o-rings with oil- and fuel-resistant construction to help maintain a tight seal during demanding engine operation.

Compatible With 2007-2010 Dodge Ram 2500, 2007-2010 Dodge Ram 3500, 2011-2019 Ram 2500, and 2011-2019 Ram 3500. The SK146 is engineered to match the mating surfaces at the injector and rail for proper fit and sealing.

Key Features

• High-temp Viton(R) o-rings for heat resistance
• Oil- and fuel-resistant rubber construction
• Designed for proper sealing between the fuel injector and fuel rail
• Black and copper seal colors for identification
• Built for one injector application
• Includes five o-rings with multiple seal sizes

Detailed Description

Standard Ignition SK146 is a fuel injector seal kit for diesel fuel system service on Ram 2500, Ram 3500, and Dodge Ram 2500/3500 models listed above. The seal set is designed around the injector and fuel rail mating surfaces to support a secure seal under high heat and fuel exposure. The kit uses rubber seals with Viton(R) material characteristics to resist breakdown from oil and fuel contact during vehicle operation. This part cross-references Dorman OE Solutions 904-315 and MAHLE GS33614 for the same application.

Common Issues This Part Can Help Address

• Fuel seepage at the injector seal area
• Hard starting caused by poor injector sealing
• Fuel odor from leaking injector o-rings
• Loss of rail seal integrity after injector service
• Air intrusion at the injector-to-rail connection

Installation Notes and Tips

Inspect the injector bore, rail sealing surfaces, and old seal remnants before installation. Clean all mating surfaces thoroughly and replace damaged seals rather than reusing them. Verify the seal sizes and orientation against the injector and rail locations before assembly. For fitment confirmation, use the vehicle year, make, model, and engine-specific service information for 2007-2010 Dodge Ram 2500/3500 and 2011-2019 Ram 2500/3500 applications.

Quality Assurance

Standard Ignition fuel injector o-ring kits are quality-tested for durability during demanding vehicle operation. SK146 is built to provide consistent sealing performance in high-heat, fuel-exposed conditions.
