You PM'ed me a picture of a pulse type fuel pump...
I think you have an electric fuel pump...
What model & serial number is your mower?
:smile:KennyV
The pump you have sounds like it is working... & will likely continue to work.
The one on eBay will likely also work...
It Could be another 10 years before you need it & then you may find that the new one doesn't ...:smile:KennyV
