AISEN FUEL LINE FILTER GROMMET KIT FOR HUSQVARNA 223L 537052301 580457501 537042401

What It Is

This AISEN kit replaces the fuel line, filter, and grommet on Husqvarna 223L and compatible trimmers/brushcutters. It delivers fresh fuel from the tank to the carburetor when the original parts get brittle, clogged, or leak.

Fitment & Compatibility

• Direct fit for: Husqvarna 223L (model year 2004 and later), 223LD, 323L, 323LD, 325L, 325LD, 326LD, 327LD X-Series, and 329LD. Also fits models using OEM part numbers 537052301, 580457501, and 537042401.
• Check before buying: Confirm your machine’s model number (stamped on the engine shroud or near the fuel tank). This kit uses a 3/16” (4.8mm) inner-diameter hose and a standard 1/4” (6.35mm) grommet hole. Measure your tank opening: if it’s larger than 7mm, you may need a different grommet.
• Not compatible with: Most 125-series, 128-series, or 130-series trimmers (they use a different tank/filter setup). Also not for 223L models built before 2004 (they used a separate fuel cap vent).

Key Things to Know

• Quality: AISEN is an aftermarket brand. The filter element is slightly smaller than OEM but works fine. The grommet is soft rubber—avoids the cracking common in old Husqvarna parts.
• Installation difficulty: Easy (15-20 minutes). You’ll need a small flathead screwdriver to pop the old grommet out and a pick or pliers to seat the new one. No special tools required.
• Common gotcha: The kit includes a short piece of fuel line. If your tank-to-carburetor distance is longer (e.g., 223L with a primer bulb), you may need to buy extra 3/16” line separately.
• Price vs. OEM: At $7.56, it’s about half the cost of a genuine Husqvarna kit. Reviews note it works as well, though the filter may need replacement slightly sooner (every 1–2 seasons vs. 2–3 for OEM).

Should You Buy It

Buy this if you need a budget-friendly, drop-in replacement for a Husqvarna 223L or compatible trimmer with a worn-out fuel system. It’s a solid value for DIYers who don’t mind aftermarket quality. Skip it if you want OEM longevity or have a rare model outside the listed compatibility—stick with genuine Husqvarna parts for those.
