HIPA (Pack of 5) Primer Bulb for Tecumseh Engine LEV80 LEV90 LV148EA LV148XA LV156EA LV156XA LV195EA LV195XA LAV100 LAV115 LAV120 Lawn Mower

What It Is

This is a pack of five primer bulbs designed for Tecumseh small engines used on walk-behind lawn mowers. The bulb manually pumps fuel into the carburetor to help start a cold engine.

Fitment & Compatibility

Before buying, confirm your engine model matches one of these: LEV80, LEV90, LV148EA, LV148XA, LV156EA, LV156XA, LV195EA, LV195XA, LAV100, LAV115, LAV120. The bulb diameter is approximately 1.25 inches. It replaces OEM part numbers 631021A, 631021, 631021B, and 632829. If your mower uses a Tecumseh engine from the 1990s or early 2000s, this bulb is likely a direct swap. Measure your old bulb’s stem length and diameter to be sure—this one fits standard Tecumseh carburetors, but some aftermarket or non-Tecumseh carbs may need a different bulb.

Key Things to Know

• Quality: These bulbs are firm, pliable rubber that hold up to fuel and sun better than some generics. Users report a tight seal without leaks.
• Installation: Easy—pop the old bulb out, push the new one in. No tools needed. Takes about 2 minutes.
• Common gotcha: If the engine still won’t prime after replacement, check for a cracked fuel line or a clogged carburetor. A new bulb won’t fix those issues.
• Pack of five: Nice to have spares, but one bulb usually lasts a season or two. Share extras with neighbors or keep for future mowers.

Should You Buy It

If you have a Tecumseh engine in the listed models and your primer bulb is cracked, hard, or won’t hold fuel, this is a cheap, reliable fix. The pack of five makes it a great value for anyone maintaining multiple mowers or helping out friends. Skip it if your engine uses a different carburetor design or if the problem is deeper (like a clogged carb or bad fuel line).
