I know zero about them. Don't even know how can tell them. I'm assuming there marked/stamped?
Do they interchange ? Or they pump specific? Reason I asked...
I have a cyclops pump. That is gutted and a computer popped up. No clue what I should look for to know if it will work on the shell of a pump I have or not. Thank you
