Good Visible Filter
Been good so far on a Hanway Scrambler 125 E4. The unit can be disassembled for cleaning / filter replacement very easily with 2 wrenches. Clear view of fuel and the filter element to see any debris. And much better than the cheap paper ones which always clog quickly.

The filters are very good in size and quality. It is good for in line filers after the feul tank and it is better to put a smaller filters forvthe feul injection

This little filter packs a punch for its size. The clear glass housing is a standout feature—it lets you easily spot debris buildup without taking anything apart. I installed it on a classic carbureted setup using 5/16" fuel line, and it fit perfectly. The replaceable mesh element is a smart touch, saving time and money down the line. Installation was a breeze—no special tools needed—and it’s held up well under regular use. It’s not designed for fuel-injected systems, but for older vehicles or small engines, it’s a reliable, budget-friendly solution. At under $10, it’s hard to beat for peace of mind and easy maintenance.
