Thanks for the post!

You can actually refer to my reply to an older post dealing with this same situation, just click on the below link:

As long as the pump is turning over, the problem must exist internally in the Pump. It's very common for the Piston Ring/Cylinder to wear down, it may not be visible to the naked eye.

Let us know if this helped you or not.
Thanks!
