Detailed Description of Dorman 904-8052 Fuel Injector O-Ring Kit

This fuel injector O-ring kit from Dorman includes six black rubber O-rings paired with six copper cups, designed to replace worn or damaged seals in fuel injectors. The rubber O-rings have precise dimensions with a 1.36-inch inside diameter, 1.57-inch outside diameter, and 0.103-inch thickness, featuring an oval rim shape to ensure a tight seal around the injector body. The copper cups complement the rubber seals by providing a robust metal barrier that resists fuel corrosion and heat exposure. This combination helps maintain proper fuel pressure and prevents leaks that can affect engine performance.

Common Applications and Issues Addressed

• Prevents fuel leaks caused by deteriorated or cracked injector seals
• Eliminates rough idling or misfires related to fuel delivery inconsistencies
• Resolves fuel odor issues due to leaking injector seals
• Helps maintain optimal fuel pressure for efficient engine operation
• Addresses injector seal wear in vehicles requiring 1.36-inch ID O-rings

Installation Notes and Tips

Before installation, clean the injector and fuel rail surfaces thoroughly to remove any debris or old sealant. Lubricate the rubber O-rings lightly with clean engine oil or recommended lubricant to ease installation and prevent damage. Carefully seat the copper cups and rubber O-rings in their respective grooves, ensuring the oval rim shape aligns correctly for a proper seal. Avoid over-tightening fuel rail bolts to prevent deformation of the new seals.
