Folks, that thread I wrote over eleven years ago revolves around a low-pressure/low-volume piston lift-pump. While I did not specify clearly what I was working with in that thread, I certainly never said nor implied it's a high-volume/low-pressure lift-pump.
As mentioned above, some months later, I posted a thread where I found that the 2nd gen piston-pumps ran a larger bore thus, a higher volume. In that thread I included a picture of the two pumps side by side with the springs (I believe it was during this time, some folks started thinking about swapping springs to come up with a HVLP pump. ).
The part numbers shown throughout my thread are for a low volume/low pressure piston pump. I think it's normally used in a agricultural application.

thanks for clarifying this, as there are hundreds of folks over the years who upgraded their diaphragm type pumps to piston lift pumps who assumed, as with any upgrade, you would be receiving some sort of extra performance, or benefit, other than replacing the stock diaphragm pump with a more, reliable piston style pump.
The benefit to these forums, besides having to read unneceasary, detracting comments such as Ofelas declaration above, are that the folks who try to help others with their quests, can inevitably learn something new in the process.
So indeed the OP can have a more reliable pump, as his original intent was, but it won't have the benefits of being a HVLP unit.
Might be beneficial to alter the sticky thread , clarifying the pump is a simple piston pump, of low volume, low pressure, so that misunderstandings can be minimized in the future.
My apologies to the OP for providing information that wasn't entirely correct.
