FAILURE out of the box and complete waste of time -- had to reinstall old Ulka pump.
I felt like the old pump in my 2007 Rancilio Silvia was getting weak.  So I purchased this new Ulka pump around the first of the year.  Since my old pump was still working, I put off installing the new pump until now.  I used a turkey baster to get the new pump primed.  But after 2-3 hours of installing, de-installing, re-installling, de-installing, and A/B testing next to the old pump,  I am now back to where I started with the old plastic-necked pump installed in the machine (funny thing is, the old pump seems to be working better after all that handling).  However, this new brass-necked pump was a complete waste of money and time for me.
