Nice Filter!
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.

Excellent filter for small outboard
I've used these filters in the past very effective and great visibility with the glass tube to see the dirt.

Good glass fuel filter
This fuel filter has great flow, easy to install but I will say after a few weeks of my truck sitting the fuel filter was leaking and it wasn’t the hoses it was the actual filter but I just had to mess around with it then it was all better. For the filter being glass and tiny it is very durable.
