The top cap includes 1″ NPT inlet and outlet fittings, enabling straightforward integration into standard fuel lines. A protective sheet helps prevent damage to the filter element under pressure, supporting reliable filtration in demanding environments.
DICMIC High Flow Fuel Filter
This high-flow cartridge is designed for mobile and stationary fuel pump tanks, offering a 1″ NPT connection and a 30-micron particulate filter. It supports applications in construction, agriculture, and other demanding settings, where clean fuel is essential to protect the fuel system. The unit is compatible with gasoline, diesel, and kerosene, and is built to maintain steady performance under pressure with reliable filtration efficiency.
Dtomi High Flow Fuel Filter
Dtomi’s high-flow filter is a 1″ NPT, 30-micron cartridge designed for diesel transfer, mobile, portable, and stationary pump tanks. It includes a cast-aluminum filter head and a spin-on style filter cartridge with standard 1 1/2”-16 UNF threads. The configuration supports up to 25 GPM with a maximum 50 PSI rating, making it suitable for robust diesel filtration needs in various equipment.
Kofil FF5369W Filter Cartridge
KOFIL’s FF5369W 20-micron filter cartridge is designed for heavy-duty diesel engines and compatible components. It uses high-efficiency filtering to capture particles that can cause fuel system wear, supporting longer life for fuel injection equipment. It cross-references multiple engine platforms, including Davco assemblies, and can work with DD13, DD15, DD16 engines and related Cummins configurations. This cartridge emphasizes filtration efficiency and cross-compatibility with a broad range of diesel systems.
ATRACYPART 1 Inch NPT Fuel Tank Filter Kit
ATRACYPART offers a complete filtration solution with a 1″ NPT cast-aluminum head and a spin-on filter. It has a 30-micron particulate rating and a flow rate of up to 25 GPM with a maximum pressure of 50 PSI. This kit is ideal for construction and agricultural applications, ensuring a reliable filtration system to protect the fuel pump and downstream components from dirt and particulates.
Buying Guide
- Micron rating: Lower micron ratings (e.g., 20 microns) provide finer filtration but may reduce flow slightly. Higher ratings (30 microns) allow higher flow while still protecting critical components in many diesel systems.
- Flow rate and pressure: Choose a filter that matches your system’s flow needs (e.g., 25 GPM) and the operating pressure (commonly up to 50 PSI for these units). Ensure compatibility with your pump and tank setup.
- Fitting size and type: Most filters use 1″ NPT connections. Confirm inlet/outlet orientation and threading before purchase to avoid modifications.
- Filter head and cartridge compatibility: Some kits include a complete head plus cartridge; others require separate components. Assess whether you need a full kit or a cartridge replacement only.
- Material and durability: Cast-aluminum heads and rugged housings improve durability in harsh environments such as construction sites and agricultural settings.
- Fuel compatibility: Verify that the filter is compatible with diesel, kerosene, or gasoline blends used in your equipment. Many products list diesel as a primary use but support other fuels as well.
- Maintenance and replacement frequency: Consider the availability of replacement elements and how easy it is to service the filter in the field or workshop.
- Application scope: Some filters are optimized for mobile, portable, or stationary diesel transfer, while others target specific engine families. Pick based on your equipment type and fuel source.
- Water separation: If you operate in damp environments or with biodiesel blends, look for filters with water separation or robust protection against water intrusion to extend injector life.
When selecting a diesel fuel filter cartridge, balance filtration efficiency, flow requirements, compatibility, and ease of maintenance. The products listed here cover a range of common diesel filtration needs, from high-flow, heavy-duty filtration to compact, kit-style solutions suitable for a variety of machines and vehicles.
