### ⭐ 1.0 out of 5 stars







  
  
    Skip it for dual!!!!!!!!!!!!
  

*by A***R on Reviewed in the United States on November 21, 2016*

Does not work on Dual pump W-40 as shown, due to design of pump/center screw, and design of/length of replacement pins that should secure diaphragm to pump are much shorter than original. You can not secure and get an airtight seal. Tried 3 times, and it blows it off every time. The original was glued at base of diaphragm, and at center screw in diaphragm to make it air tight and secure. No way to do that on the replacement, used super glue as well in final attempt, and it still blows air out of the side. So frustrating!!!! Luckily, I had an old pump to use for air for now until new pump arrives, otherwise I would have been SOL. Save your $ and buy a new pump rather than try this fix for the dual setup. I have fixed other pumps in the past, and did not have such problems.

### ⭐⭐⭐⭐ 4.0 out of 5 stars

The item was not the same size as the one I previously had, however I was able to stretch it into place and it got the job done. It was very easy to install.
