Standard Motor Fuel Injector O-Rings

Replace your worn, cracked, or damaged fuel injector O-rings with Standard Motor Products. Your vehicle's fuel injectors operate under extreme pressures and are fitted with several O-rings to prevent leakage of fuel into hot engine compartments. The operating conditions are tough on sealing materials, and O-rings must be capable of sealing from as low as -40 degrees C to as high as +150 degrees C and be highly resistant to aggressive automotive fuels. The consequence of O-ring failure could be catastrophic, so trust your engine to Standard Motor Products O-rings.
