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.

Clear Glass; Easy to See
Fits 5/16 line really well with clamps. I put the filter on the other side of the primer bulb so that when I do use it, it sucks the fuel through the filter. Looks great. Can see how clear you gas is. Got a pack of the 3 pack filters as well so I can change when needed.

Bigger than expected but works for my purpose.
Installed this inline before my evap valve solenoid in my Infiniti i35 to clear p1444. It worked, and the code went off on its own after a couple days of driving. Only reason I gave it 4 stars instead of 5 is bc the filter was bigger than I expected.. (My fault for not checking measurements beforehand.) It did end up fitting w/o any leaks, but it was definitely a tighter fit than I had hoped for. Still works though, no leaks, and adding this filter cleared the p1444 so I cannot complain! Definitely recommend this for anyone who has replaced the evap solenoid sensor but is still getting p1444. (Will post picture later to give a visual of where to install the filter.)

Nice see through glass.
Makes a nice sight glass. I'm using on old Jeep as a quick visual indicator that fuel is getting to carburetor.
