12V DC Fuel Polishing Transfer System

Restore and maintain the quality of your stored diesel fuel with this portable 12V DC Fuel Polishing and Transfer System. Contaminated fuel is one of the leading causes of costly engine failures, and this compact unit provides a complete solution. Featuring a self-priming 12V DC pump, it circulates diesel from storage tanks, removing water, rust, sludge, and microbial growth.

The system uses a high-efficiency Baldwin BT8448 fuel filter that traps particulates down to 20 microns while separating both free and emulsified water. An integrated pressure gauge makes filter service simple by showing exactly when replacement is needed. Built with durable fittings and a sturdy mounting bracket, this system is ideal for mobile, remote, and industrial applications where clean, reliable fuel is critical.

How It Works

This fuel polishing system operates by pulling diesel from your storage tank with a powerful 12V DC self-priming pump. Once drawn in, the fuel passes through a Baldwin BT8448 water-separating filter. This filter is highly efficient and removes harmful contaminants such as water, rust, sludge, and microbial growth that commonly form in stored diesel. The system also includes a built-in pressure gauge, which provides a real-time reading of the filter’s condition. When the gauge moves into the yellow or red zone, you’ll know it’s time to change the filter, ensuring maximum efficiency and protection for your fuel.

Why Use It

Diesel fuel that sits in storage tanks often becomes contaminated with water, particulates, or microbial growth. These impurities can cause clogged injectors, reduced engine performance, and even complete engine failure. By using this kit, you can prevent these issues before they happen. Clean fuel means reliable engine starts, smoother operation, and longer engine life. It also saves you money by reducing maintenance costs and downtime caused by fuel-related failures.

Application

This system is versatile and suitable for a wide range of industries and uses, including:

• Marine vessels and yachts – Protect engines from fuel contamination while at sea.

• Emergency backup generators – Ensure power systems start up reliably when needed.

• Construction equipment and heavy machinery – Maintain performance in tough environments.

• Farms and agricultural equipment – Keep tractors and harvesters fueled with clean diesel.

• Remote and off-grid sites – Ideal for locations where AC power is not available.

How to Use It

1. Connect the unit’s power leads directly to a 12V battery.

2. Attach the inlet hose to your fuel tank and the outlet hose to the receiving tank or back to the same tank (for polishing).

3. Turn on the pump to start circulating the fuel through the filter system.

4. Monitor the pressure gauge during operation to know when the filter needs servicing.

5. Replace the filter once the gauge indicates it is clogged, ensuring continued peak performance.
