Ive been doing some searching on the forum and cant come accross anyone running one of these pumps with the upgraded pressure relief valve. Other than cost i wanted to see if there is a reason why people seem to be skipping on the upgraded valve before i purchase one

 

These are new, not sure

 

They are a relatively new option. I don't know of anyone that has run one yet.

 

I have one in Acamas, no issues to report.
