Product Details

The Bosch 0438170034 Fuel Pressure Accumulator is a critical component of continuous injection systems (CIS) and K-Jetronic fuel injection systems. This fuel accumulator maintains residual fuel pressure in the system after engine shutdown, preventing vapor lock and ensuring quick, reliable starts.

Key Features:

  • Maintains constant fuel system pressure for optimal performance
  • Prevents fuel line vapor formation during hot restarts
  • Dampens fuel pressure pulsations for smoother operation
  • Direct OE replacement for worn or leaking original accumulators
  • Precision-engineered to Bosch OE specifications

This fuel pressure accumulator is designed to store fuel under pressure using an internal diaphragm and spring mechanism. When the fuel pump stops, the accumulator maintains system pressure to keep fuel lines primed and prevent air intrusion. Common failure symptoms include hard starting when hot, extended cranking time, and fuel pressure loss after sitting.

I ordered a Warn Winch remote control system for a winch that will be used in a trailer. Price was the best I found and shipping was also. Great company to deal with and I will check them out on all my future purchases.

I am pleased with Autoplicity. There was a miscommunication on shipment, but after a phone call, everything was handled. Looking forward to my parts coming in. Thanks guys!
