The spacer between the regulator spring and the diaphragm comes in two versions, see picture. Is the one with more chamfering the latest version? Does both versions work OK?

Hello,

I got a new pump form Yamada and it has the one on the right, I have not seen the one on the left yet, wich version of the 170 was it on?

Regards
