What Is the Fuel Pump 9580810019?

The part number 9580810019 (also written as 9 580 810 019) is a Bosch electric fuel pump designed for fuel injection systems. It is commonly used in the JEEP CHEROKEE and other vehicles that require a reliable, high-flow fuel pump . This pump is an electric unit that transfers fuel from the tank to the engine, maintaining proper pressure for efficient combustion.

The pump is manufactured by Bosch, a leading supplier of automotive fuel systems. Bosch fuel pumps are known for their durability and precision engineering, and many aftermarket modules are made on the same production lines that serve original equipment manufacturers (OEM) . The 9580810019 is a direct replacement part that meets or exceeds OEM specifications.

Key Specifications and Applications

The fuel pump 9580810019 is an electric fuel injection pump that operates at 12V and delivers a shut-off pressure of 6 bar with a wide open flow of 160 L/h . It is designed for use in a variety of vehicles, including:

  • Jeep Cherokee (most common application)
  • Toyota and Honda models (cross-referenced applications)
  • General Motors vehicles (some applications)

The pump is available as an aftermarket replacement part from multiple suppliers, and it is certified with quality standards such as ISO 9001 and TS16949 . This ensures that the pump meets strict manufacturing and reliability requirements.

Symptoms of a Failing Fuel Pump

If your vehicle is experiencing any of the following issues, the fuel pump 9580810019 may need to be replaced:

  1. Hard Starting or No Start: The engine cranks but takes a long time to start, or it does not start at all. This is a classic sign of low fuel pressure .
  2. Engine Sputtering or Stalling: The engine may sputter at high speeds, lose power during acceleration, or stall unexpectedly, especially when the fuel tank is low .
  3. Loss of Power Under Load: You may notice a lack of power when climbing hills or carrying a heavy load.
  4. Whining Noise from the Fuel Tank: A loud whining or humming sound coming from the rear of the vehicle indicates that the pump is working harder than it should.
  5. Rough Idle or Surge: The engine may idle roughly or surge without any apparent reason.

According to Bosch, over half of all fuel pump replacements are the result of misdiagnosis . Before replacing the pump, check other components such as the fuel filter, fuel pump relay, and security system to ensure the pump is actually the culprit.

How to Replace the Fuel Pump 9580810019

Replacing a fuel pump is a job that many DIYers can handle, but it requires careful attention to safety. Here are the basic steps:

  1. Relieve Fuel System Pressure: Disconnect the fuel pump fuse or relay, then start the engine and let it run until it stalls. This releases pressure in the fuel lines.
  2. Disconnect the Battery: Always disconnect the negative battery terminal before working on the fuel system.
  3. Access the Fuel Pump: The pump is typically located inside the fuel tank. On most vehicles, you can access it through an access panel in the trunk or under the rear seat. On some models, you may need to drop the fuel tank.
  4. Remove the Old Pump: Disconnect the electrical connector and fuel lines, then remove the retaining ring and lift out the pump assembly.
  5. Install the New Pump: Install the new Bosch 9580810019 pump in the reverse order. Make sure to replace the fuel filter and clean the fuel tank to reduce debris and contamination .
  6. Test the System: Reconnect the battery, turn the key to the "ON" position (without starting), and check for fuel leaks. Then start the engine and verify proper operation.

Preventing Fuel Pump Failure

To extend the life of your new fuel pump, follow these simple tips:

  • Avoid running on low fuel: Frequently driving with a low fuel tank can cause the pump to overheat and wear out faster .
  • Replace the fuel filter regularly: A clogged filter forces the pump to work harder, leading to premature failure.
  • Keep the fuel tank clean: Contamination from dirt, rust, or debris is one of the top causes of pump failure .
  • Use high-quality fuel: Poor-quality fuel can contain contaminants that damage the pump over time.

Why Choose a High-Performance Aftermarket Fuel Pump?

If you are looking for more than just a direct replacement, consider upgrading to a high-performance fuel pump. Aftermarket pumps offer several advantages:

  • Higher flow rates: Performance pumps deliver more fuel per hour, which is essential for modified engines or vehicles that require extra fuel under heavy load.
  • Better durability: Many aftermarket pumps use premium materials and advanced designs to withstand high temperatures and continuous use.
  • E85 compatibility: Some pumps are designed to work with ethanol-blended fuels like E85, which can be corrosive to standard pumps.
