Before starting the screw pump, liquid must be injected into the pump body through the inlet to prevent dry running, which can lead to wear and damage to the screw pump stator. Prior to starting the screw pump, it is essential to ensure the direction of rotation is correct. The screw pump should not be operated in reverse. For newly installed .
Adjusting the fuel screw on a 12v Cummins VE pump is a critical step in fine-tuning the performance of your diesel engine. Whether you are looking to improve fuel efficiency, increase power output, or simply optimize the engine's performance, adjusting the fuel screw can make a significant difference. In this article, we will discuss the process of adjusting the fuel screw on a 12v Cummins VE pump, along with a detailed tuning diagram to guide you through the process.

VE Pump Adjustment
The VE (rotary) pump is a popular injection pump used in many Cummins engines, including the 6BT. The fuel screw on the VE pump controls the amount of fuel that is delivered to the injectors, and adjusting this screw can have a direct impact on the engine's performance. To adjust the fuel screw on a 12v Cummins VE pump, follow these steps:
1. Locate the fuel screw on the side of the VE pump. It is typically a slotted screw that can be turned using a screwdriver.
2. Before making any adjustments, it is important to ensure that the engine is at operating temperature and idling smoothly.
3. To increase fuel delivery and power output, turn the fuel screw clockwise. To decrease fuel delivery and improve fuel efficiency, turn the fuel screw counterclockwise.
4. Make small adjustments to the fuel screw, no more than a quarter turn at a time, and monitor the engine's performance after each adjustment.
5. It is recommended to use a tachometer to monitor the engine speed while making adjustments to ensure that the engine is running at the desired RPM.
VE Pump Tuning Diagram
A tuning diagram can be a useful tool to guide you through the process of adjusting the fuel screw on a 12v Cummins VE pump. Below is a basic tuning diagram that outlines the steps involved in fine-tuning the fuel delivery of the VE pump:
1. Start by setting the fuel screw at the factory recommended position. This will serve as a baseline for further adjustments.
2. If you are looking to increase power output, gradually turn the fuel screw clockwise in small increments, monitoring the engine's performance after each adjustment.
3. If you are aiming to improve fuel efficiency, turn the fuel screw counterclockwise to reduce fuel delivery.
4. It is important to strike a balance between power output and fuel efficiency by fine-tuning the fuel screw based on your specific performance goals.
