partszen Air Filter Primer Bulb Kit for Husqvarna 340 345 350 351 353 — Complete Air & Fuel Tune-Up

This compact replacement kit includes an air filter, fuel filter, primer bulb, spark plug and two fuel lines. It’s intended as a direct-fit swap for specific Husqvarna two-stroke saw models, restoring proper air and fuel delivery when the original filter or primer becomes worn, clogged or damaged. Because there are two different connector styles for this air filter family, confirm your existing connector matches the design pictured before purchase—this kit does not fit Husqvarna 350 models from 2005 and is not compatible with Redmax G5300 chainsaws or parts numbered 537264903.

How do I know this kit fits my Husqvarna chainsaw?

Check the part numbers and visual connector style on your existing air filter. This partszen kit replaces Husqvarna part numbers 537024002 and 537024003; if your OEM part is 537264903 or a different connector type, this kit will not match.

• Compatible with Husqvarna 340, 345, 346xp, 350 (non-2005), 351 and 353
• Replaces OEM 537024002 and 537024003 only
• Not compatible with Husqvarna 350 (2005) or Redmax G5300
• Compare connector shape to your current part before ordering

What parts are included and why they matter?

The kit contains an air filter, a fuel filter, a primer bulb, a spark plug and two fuel lines—everything needed to refresh basic fuel and air system components in one go. Replacing these small components together helps ensure consistent starting and running because clogged or degraded parts often fail in combination.

• 1x air filter for proper air filtration and engine protection
• 1x fuel filter to prevent debris reaching the carburetor
• 1x primer bulb to assist fuel delivery during cold starts
• 1x spark plug and 2x fuel lines for a more complete tune-up

How do I install the air filter and primer bulb?

Installation is straightforward for anyone familiar with backyard chainsaw maintenance: remove the top cover, unclip the old filter and disconnect the fuel lines, then fit the new parts in reverse order. If you’re unsure, follow the chainsaw’s service manual or consult a technician to avoid misrouting lines or damaging connectors.

• Remove cover and note fuel line routing before disconnecting
• Replace air filter and seat it securely in the housing
• Install primer bulb and reconnect fuel lines to original positions
• Test by priming and checking for proper fuel flow before use

Will this kit improve starting and engine performance?

Fresh filters, a new primer bulb and a clean spark plug can improve starting consistency and help the engine run more smoothly by ensuring correct air–fuel balance and ignition. However, results depend on the overall condition of your chainsaw and proper installation; this kit addresses common wear items, not major mechanical issues.

• New air and fuel filters reduce clogging and lean/rich running issues
• Primer bulb restores easier cold starts and fuel delivery to the carburetor
• Spark plug renewal supports reliable ignition and smoother idle

Who is this for: This partszen kit is aimed at home owners, landscapers and small tree-care pros who own compatible Husqvarna saws and need an economical way to replace worn air and fuel components. It’s best for users who can identify OEM part numbers or visually verify their existing connector style; if you have a Husqvarna 350 from 2005 or an incompatible part number, consider alternative replacement kits.
