Fuel accumulator for Mercedes Jetronic injection systems<\/strong><\/p>\n

This high-quality fuel accumulator is suitable for classic Mercedes models with a Bosch K-Jetronic or KE-Jetronic injection system. The accumulator ensures that the fuel system remains under pressure after the engine is switched off, which is essential for a reliable warm start and stable operation of the injection system.<\/p>\n

A properly functioning fuel accumulator prevents pressure loss and helps prevent vapor formation in hot fuel lines. As a result, the fuel supply remains reliable even after a period of inactivity.<\/p>\n

Main function of the fuel accumulator<\/strong><\/p>\n

\u2022 Maintains residual pressure in the fuel system.
\n\u2022 Prevents pressure loss after switching off the engine.
\n\u2022 Reduces the risk of vapor formation in hot fuel lines.
\n\u2022 Supports a fast and reliable warm start.
\n\u2022 Contributes to the stable operation of the injection system.<\/p>\n

Suitable for Mercedes models<\/strong><\/p>\n

\u2022 Mercedes SL (R107)
\n\u2022 Mercedes SLC (C107)
\n\u2022 Mercedes S-Class (W116)
\n\u2022 Mercedes G-Class (W460)
\n\u2022 Mercedes G-Class Convertible (W460)
\n\u2022 Mercedes W123 Sedan
\n\u2022 Mercedes C123 Coup\u00e9
\n\u2022 Mercedes S123 T-Model (Estate)<\/p>\n

Always check the OEM part number before ordering to determine the correct application.<\/p>\n

Symptoms of a defective fuel accumulator<\/strong><\/p>\n

\u2022 Difficulty starting with a warm engine.
\n\u2022 Long start time after a short standstill.
\n\u2022 Loss of fuel pressure.
\n\u2022 Irregular engine running immediately after starting.
\n\u2022 Residual pressure disappears too quickly after switching off the engine.<\/p>\n

Important regarding replacement<\/strong><\/p>\n

    \n
  1. Work cleanly and prevent contamination of pipes and connections.<\/li>\n
  2. Check the fuel lines for leaks and aging.<\/li>\n
  3. Check the operation of the fuel pump and the fuel filter.<\/li>\n
  4. After installation, check all connections under system pressure.<\/li>\n
  5. Check whether the fuel system maintains the prescribed residual pressure.<\/li>\n<\/ol>\n

    Advice<\/strong><\/p>\n

    A defective fuel accumulator is not the only possible cause of hot start problems. A worn fuel pump, a defective check valve, leaking injectors, or a malfunctioning pressure regulator can also cause similar symptoms. Therefore, always check the entire fuel system during diagnosis.<\/p>\n

    Important<\/strong><\/p>\n

    Always check before purchase and installation whether the part is suitable and equivalent based on photos, description, and specifications; installed or used parts cannot be returned.<\/p>","protected":false},"excerpt":{"rendered":"
