3-Pack Universal Fuel Primer Bulb Replacement – Compatible with Homelite, Ryobi, Poulan, Craftsman, Zama, Walbro Carburetors for Blowers, Brushes, Trimmers, Gas Cutters

What It Is

A set of three universal fuel primer bulbs designed to replace worn-out bulbs on small engines. They are intended for handheld equipment like leaf blowers, string trimmers, brush cutters, and gas cutters that use Zama or Walbro carburetors.

Fitment & Compatibility

Before buying, check the carburetor model—these bulbs are compatible with Zama and Walbro carburetors found on Homelite, Ryobi, Poulan, and Craftsman equipment. Measure the bulb’s base diameter (typically 1.18 inches) and the nipple height (around 0.55 inches). Verify your machine’s brand and model number against the listing’s fitment chart, as not all universal bulbs fit every housing. If your carburetor uses a different bulb size or shape, this pack won’t work.

Key Things to Know

• Quality: These are aftermarket replacements, not OEM. They may feel slightly less durable but generally function well for the price.
• Installation: Simple—remove the old bulb, clean the carburetor surface, and press the new one in. No tools required.
• Common gotcha: The bulb must sit flush; if it’s too tight or loose, the primer won’t seal, causing fuel leaks or hard starts.
• Value: Three bulbs for under $5 means you have spares for future failures on the same or different equipment.

Should You Buy It

If you have a compatible small engine tool with a failing primer bulb and want a cheap, no-fuss fix, this pack is a solid choice. It’s ideal for DIYers who own multiple brands of handheld equipment and need a quick, universal solution. Avoid it if you require an exact OEM fit or a bulb for a non-standard carburetor.
