which part did you replace it with? the block is a custom one (i asked coolIT who made it but they dont sell them and said id need to contact cointerra support) and i couldnt find any alternative blocks with integrated 3 pin pumps that looked decent or have you just got an external pump?
Considering how bad they are, I wouldn't replace them with the same model.
EK blocks should fit but I'm yet to install it (it might require some modifications but nothing complex).
