Bosch 0438170009 Fuel Pressure Accumulator

The Bosch 0438170009 Fuel Pressure Accumulator is a critical component designed for K-Jetronic continuous injection systems. This accumulator maintains residual fuel system pressure after engine shutdown, ensuring quick restarts and preventing vapor lock in the fuel system.

Key Features:

• Maintains fuel system pressure between engine starts for improved hot restart performance
• Dampens fuel pressure pulsations from the fuel pump for smoother injection system operation
• Prevents fuel vapor formation in the system during hot conditions
• Genuine Bosch OE quality construction for reliable performance
• Direct replacement for worn or failed original accumulator

This fuel pressure accumulator is an essential component in maintaining proper fuel injection system operation. A failing accumulator can result in hard starting, particularly when the engine is hot, rough idle, or poor engine performance. Regular replacement as part of fuel system maintenance helps ensure reliable vehicle operation.
