At Guangzhou Pinxin Engine Co., Ltd., we understand that the performance and longevity of a diesel engine depend on the quality and reliability of every single component. Today, we're focusing on some critical parts for the widely-used Cummins K19 and NT855 series engines: the Fuel Oil STC Connector (3627044) and the Diesel Engine Supply Tube (3054260). These aren't just parts; they are the heart of the fuel delivery system, ensuring that your engine receives the precise amount of fuel it needs to operate efficiently and reliably.
The Cummins K19 and NT855 engines are renowned for their power and durability in demanding applications, from heavy-duty trucks to power generation. However, their high performance is only possible with a meticulously maintained fuel system. A failing connector or a compromised supply tube can lead to a host of problems, including fuel leaks, poor engine performance, and even catastrophic failure. This is why using genuine or high-quality replacement parts is non-negotiable.

To help you find the right parts quickly and efficiently, we have compiled a table with the key product details. Each component plays a vital role in the engine's fuel system.
| # | Product Name | Part Number | Engine Model |
|---|---|---|---|
| 1 | Cummins Fuel Oil STC Connector | 3627044 | K19, NT855 |
| 2 | Cummins Diesel Engine Supply Tube | 3054260 | K19, NT855 |
The Fuel Oil STC Connector (3627044) is crucial for a secure and leak-free connection within the fuel system. Its design ensures a tight seal, preventing fuel from escaping and air from entering the system, which could lead to engine misfires or stalling. The Diesel Engine Supply Tube (3054260), on the other hand, is the conduit that delivers fuel from the tank to the injection pump. It must withstand high pressure and vibration without cracking or failing, a testament to its robust construction.
Choosing high-quality, reliable components is not just about maintenance; it's about making a smart investment in your engine's future. By using superior parts like those offered by Guangzhou Pinxin Engine Co., Ltd., you can reduce downtime, lower operational costs, and extend the life of your valuable Cummins K19 or NT855 engine. Our commitment to providing parts that meet or exceed OEM standards ensures that you get the best performance and peace of mind.
