• Dorman 904-8053 replacement part for injector seal service

Detailed Description

Dorman 904-8053 is engineered to provide the O-rings required for a complete fuel injector seal replacement on the specified engine. The rubber material is selected to handle exposure to extreme temperatures as well as contact with fuel and oil, which is important for maintaining injector sealing performance over time. For technicians servicing Honda Civic or Toyota Corolla fuel injector systems, this kit supports a clean reseal when injector O-rings show age-related wear, flattening, or cracking. This part cross-references 3070136 for the same application.

Common Repair Uses

• Fuel odor caused by leaking injector seals
• Hard starting related to injector seal leakage
• Visible fuel seepage around injector bases
• Rough idle from vacuum or fuel sealing issues at the injector
• Maintenance during injector removal and resealing service

Installation Notes and Tips

Inspect the injector bore and rail surfaces before installation, and replace damaged seals rather than reusing old ones. Lightly lubricate the O-rings with clean engine oil or a fuel-safe lubricant during assembly to reduce pinching and help the seals seat correctly. Confirm the injector and engine application before installation, and verify that the O-ring sizes match the original components on the vehicle.
