11QG70120 Hyundai Fuel Filter
First and foremost, the 11QG70120 is a reliable aftermarket Hyundai fuel filter built for heavy-duty diesel equipment. Moreover, this 11QG70120 replacement fuel filter delivers stable protection across construction, marine and generator fleets. In addition, it works perfectly as a cost-effective solution without relying on factory original parts. Therefore, it suits routine maintenance for workshops and large equipment fleets alike. Meanwhile, this guide covers its full specs, working principle and cross-model compatibility clearly.
Core Technical Specifications
To begin with, precise dimensions ensure smooth installation inside standard fuel filter housings. Furthermore, every measurement matches industry mounting standards for direct drop-in replacement:
- Outer Diameter: 111 mm (4.37 inch)
- Inner Diameter: 21 mm (0.83 inch)
- Overall Length: 120 mm (4.72 inch)
- Particle Efficiency: 95% at 30 micron
- Emulsified Water Separation Efficiency: 95%
Besides, these accurate sizes allow quick swap procedures without extra modification work. As a result, maintenance teams can finish filter changes faster on busy job sites.
Working Principle of 11QG70120 Fuel Filter
In general, clean diesel fuel directly protects injectors and engine internal components. Additionally, the 11QG70120 high efficiency fuel filter combines particle trapping and water removal in one integrated design.
Fuel Flow Filtration Process
At first, contaminated diesel enters the filter housing from the fuel supply line. Next, fuel flows through the outer pleated media layer gradually. Then, large solid particles get blocked on the surface structure immediately. After that, fine contaminants down to 30 microns are trapped deep inside the fiber material. Finally, purified fuel moves toward injectors while separated water settles at the bottom chamber naturally.
Particle Contaminant Removal
On one hand, metal debris, rust and dust are intercepted on the outer media surface. On the other hand, tiny fine particles are filtered through multi-layer depth filtration. For this reason, the filter reaches a steady 95% filtration rate for 30‑micron impurities. What is more, the high-capacity pleated design extends service intervals effectively. Consequently, it reduces frequent replacement cycles for long working hours.
Water Separation Performance
Normally, emulsified water inside diesel easily damages fuel systems and shortens engine life. Luckily, this filter features strong water separation ability. In fact, it achieves 95% efficiency for removing emulsified water from low-quality diesel. Hence, it prevents corrosion, injector sticking and unstable engine power in humid environments.
