These are just what we needed! My husband lost the little primer bulb to the oil reservoir cap on his off-brand mini 8 inch chainsaw. We had bought the chainsaw from Amazon but they no longer carry it or any items from that particular offbrand. Because the pump bulb we needed was for a 1/2" cap, most of the ones listed on Amazon were too large. Thankfully, we found this multipack for a small amount of money. The .55" cap works perfectly on his chainsaw! And now, we have extra replacements for it as well as other sizes that will work well for his other tools. Very pleased with this purchase!!!

It is a set of 4 different sizes of priming bulb. It fit perfectly my application. Unless one is sure of the exact size needed, I recommend the purchase of this kit.

Hace el trabajo y encajan bien.

I used it to replace the primer bulb on my 2-stroke Ryobi Jet Fan leaf blower. The old bulb was cracked so when running the blower would not come up to full speed and/or would stall because the carb was sucking air through the old, cracked bulb. I replaced the old bulb, the blower started right up, and I was able to immediately spool it up to full speed. Woohoo!!! :-)

The one I needed fit very well and I a whole bunch for other tools if needed and comes in a little case so you don’t lose them
