Works just like it was supposed to

Says it has stainless steel springs but there are not any. Without springs the pump must be held upright to work correctly

This is the best Primer Bulb I have had on my boat. Others that I have purchased don’t last past a year. This is more expensive but obviously higher quality. Keeps the prime and lasts.

How about a cheaper primer bulb I guess you get what you pay for this one seems to work as expected.

Seems to be good…. old one was hard…. this one pumps gas to the carbs

Works well

The barbs are the correct size and it seems to work really well without leaks on my boat. I noticed the black rubber ones over time always leave black on my hands after they get older and the UV starts to break the rubber down- this one so far does not! Plus it looks cool being blue.No leaks, no dirty hands, pumps fuel, and the right size. What more can you ask for?

I put it on my UTV Rhino to pump gas from the tank to the carburetor , apparently it’s a problem with all Rhino’sThe bulb seems to work but when I’m pumping it I can see the gas moving back & forth in the float bowl which I don’t think it’s supposed to do.I’ll try it a few times to make sure that it works well enough to keep!Well I reinstalled it & it only works if it’s horizontal with the bulb arrow pointing downward.It should work at any angle.
