Fuel Injection Pump 9521A300T 348-6930 3486930 Compatible with Caterpillar CAT DE220E0 Engine C7.1
Generic 1. OEM-level performance and precise fuel injection: Utilizing high-pressure direct injection technology (2000-3000 PSI operating pressure), this engine matches the ECU's fuel curve to ensure fuel atomization comparable to OEM fuel. An internal precision plunger assembly achieves a flow rate error of ≤3%, improving combustion efficiency, reducing fuel consumption and emissions, and boosting power response by 15%. || 2. Premium Materials, Ultra-Long Service Life Pump Body: CNC-machined aircraft aluminum alloy, corrosion resistance five times greater than ordinary materials Key Components: Imported German bearings + ceramic plunger, 800-hour endurance test-passed Sealing System: Viton fluoroelastomer seals, resistant to ethanol gasoline and extreme temperatures || 3. Intelligent Diagnosis, Plug-and-Play Installation Built-in pressure sensor self-calibration system, compatible with OBDII diagnostics Included installation and positioning fixture, 90% of vehicle models can be replaced DIY in less than 30 minutes || 4. Triple Noise Reduction Design, Quiet Operation First Layer: Hydraulic shock valve reduces pressure pulses Second Layer: Noise-absorbing composite housing Third Layer: Optimized gear transmission structure, operating noise ≤65dB || 5. Five-Year Warranty, Professional Technical Support: This is an industry-leading five-year warranty and comes with a complimentary fuel system cleaner. Expert hotline guidance is available to troubleshoot issues such as "difficult cold start" and "low high-pressure rail pressure." Return and exchange services are available with inspection reports.

Shutoffs
The shutoffs are electrically operated or mechanically operated. The electrically operated shutoffs are controlled by the ECM.Shutoffs are set at critical levels for the following items:
Operating temperature
Operating pressure
Operating level
Operating rpmThe particular shutoff may need to be reset before the engine will start.
Always determine the cause of the engine shutdown. Make necessary repairs before attempting to restart the engine.
Be familiar with the following items:
Types and locations of the shutoff
Conditions which cause each shutoff to function
The resetting procedure that is required to restart the engineAlarms
The alarms are electrically operated. The operation of the alarms is controlled by the ECM.The alarm is operated by a sensor or by a switch. When the sensor or the switch is activated, a signal is sent to the ECM. An event code is created by the ECM. The ECM will send a signal in order to illuminate the lamp.Your engine may be equipped with the following sensors or switches:Coolant level - The low coolant level switch indicates when the coolant level is low.Coolant temperature - The coolant temperature sensor indicates high jacket water coolant temperature.Intake manifold air temperature - The intake manifold air temperature sensor indicates high intake air temperature.Intake manifold pressure - The intake manifold pressure sensor checks the rated pressure in the engine manifold. Fuel rail pressure - The fuel rail pressure sensor checks for high pressure or low pressure in the fuel rail.Engine oil pressure - The engine oil pressure sensor indicates when oil pressure drops below rated system pressure, at a set engine speed.Engine overspeed - If the engine rpm exceeds the overspeed setting, the alarm will be activated.Air filter restriction - The switch checks the air filter when the engine is operating.User-Defined switch - This switch can shut down the engine remotely.Water in fuel switch - This switch checks for water in the primary fuel filter when the engine is operating.Fuel temperature - The fuel temperature sensor monitors the pressurized fuel in the high-pressure fuel pump.Note: The sensing element of the coolant temperature switch must be submerged in coolant in order to operate.Engines may be equipped with alarms in order to alert the operator when undesirable operating conditions occur.
When an alarm is activated, corrective measures must be taken before the situation becomes an emergency in order to avoid possible engine damage.
If corrective measures are not taken within a reasonable time, engine damage could result. The alarm will continue until the condition is corrected. The alarm may need to be reset.Testing
Turning the keyswitch to the ON position will check the indicator lights on the control panel. All the indicator lights will be illuminated for 2 seconds after the keyswitch is operated. Replace suspect bulbs immediately.Refer to Troubleshooting, KENR9111 for more information.
