The fuel pump assemblies identified by part numbers 0000901202 and H11K02 represent specific automotive components engineered for precise fuel delivery requirements in particular vehicle applications. These part numbers designate complete fuel pump modules that integrate multiple components including the electric fuel pump itself, fuel level sending unit, filter elements, pressure regulator, and mounting assembly specifically configured for exact vehicle model fitment. The engineering specifications for these assemblies encompass flow rate requirements typically between 80-150 liters per hour depending on application, operating pressure ranges generally 3.5-5.0 bar for port fuel injection systems or significantly higher for direct injection applications, electrical characteristics including current draw and connector configurations, and physical dimensions ensuring proper tank mounting and seal integrity. Material compatibility addresses modern fuel formulations including ethanol-blended gasoline up to E85, with components constructed from specialized plastics, composites, and metals resistant to fuel exposure and environmental conditions within the fuel tank. Performance validation involves comprehensive testing including flow rate verification across voltage ranges, pressure regulation accuracy, durability testing through thermal cycling, and compatibility with various fuel additives. A documented case from automotive service networks demonstrated how precise replacement of these specific pump assemblies resolved drivability issues including hesitation under acceleration and hard starting conditions that generic replacements failed to address properly. Installation protocols emphasize proper sealing surface preparation, correct electrical connection engagement, and systematic pressure testing following replacement to verify system integrity. Our technical capabilities include comprehensive coverage of specific fuel pump applications with particular attention to exact OEM specifications for performance characteristics and physical dimensions.
