Standard Ignition SK138 Diesel Fuel Injector Installation Kit

Diesel Injector Seal Kit for Ford Super Duty

Standard Ignition SK138 is a diesel fuel injector installation kit built around high-temperature Viton o-rings and oil- and fuel-resistant sealing materials. It is made to maintain a tight seal between the injector and fuel rail in demanding engine conditions, including the Ford F-250 Super Duty and Ford F-350 Super Duty applications listed below.

• High-temp Viton o-rings for sealing in elevated heat
• Oil- and fuel-resistant construction for durability in diesel service
• Engineered to match injector-to-fuel-rail mating surfaces
• Quality-tested for long service life under vehicle operation
• Steel construction noted in product attributes

Application Details

Use Standard Ignition SK138 when servicing diesel injector sealing on 2011-2019 Ford F-250 Super Duty and 2011-2019 Ford F-350 Super Duty models. Fitment is listed for cylinders 1, 2, 7, and 8, making this a direct-match service kit for those specific injector positions on Ford Super Duty diesel applications. This part cross-references Dorman - OE Solutions 904-275 for the same application.

What It Helps Address

• Fuel seepage at the injector-to-rail sealing point
• Hard starting caused by compromised injector seals
• Diesel odor or visible wetness around injector connections
• Seal breakdown from heat, fuel exposure, or oil contamination
• Service issues during injector removal and reinstallation on Ford F-250 Super Duty and Ford F-350 Super Duty engines

Installation Notes

Inspect the injector bore, rail sealing surface, and surrounding components before installation. Clean all mating surfaces thoroughly and replace worn seals during injector service to help maintain proper sealing. Verify cylinder-specific application before ordering; Standard Ignition SK138 is listed for cylinders 1, 2, 7, and 8 on the covered Ford Super Duty models.

Quality Assurance

Standard Ignition states that the sealing materials are tested for durability and built to withstand extreme heat, fuel exposure, and oil exposure during vehicle operation. The SK138 is designed as a service-grade diesel injector installation kit for consistent sealing performance in Ford Super Duty diesel maintenance.
