Are you dealing with a leaking fuel injector? A failing fuel injector seal causes reduced engine performance, rough idling, misfires, and poor fuel economy due to leaks, which can lead to engine damage if ignored. The MAHLE B33845 Fuel Injector Seal is designed to help prevent fuel leaks and maintain correct injector operation. Over time, injector seals can become brittle or damaged from heat and pressure, allowing fuel or combustion gases to escape and potentially affecting engine performance. Replacing worn seals with high-quality OE-style replacements helps maintain proper fuel system sealing and ensures your injectors continue to operate efficiently. Designed for trucks equipped with the 6.7L Powerstroke diesel engine, this injector seal provides dependable sealing performance during injector service, repairs, or routine maintenance.

Manufactured from durable, molded rubber and engineered to meet original equipment specifications, the MAHLE B33845 is built to withstand the extreme temperatures, pressures, and vibrations found in modern diesel fuel systems. The precision-formed seal maintains consistent contact with mating surfaces to help prevent fuel leaks while supporting proper injector seating and operation. Designed as a direct-fit replacement, it installs easily during injector service and helps restore factory-level sealing reliability. By ensuring a tight seal around the injector, this component helps maintain proper fuel delivery, protects surrounding engine components, and supports long-term performance in your 6.7L Powerstroke engine.
