The pump components are made out of metal. Metal does not experience any significant expansion(at least at the temperature differences and measuring accuracy that we are using). If it did then all of our bridges would pop in the summer when the metal expanded and put more pressure on the rivets.
I would say that you are off on a number of your topics. There are people in America who believe that ANY form of immigration, not just illegal immigration, is ruining our country. I'm for stopping illegal immigration, if you count making all immigration legal. Sure, I don't like terrorism, but that doesn't mean I'm necessarily willing to do anything about it (if it means compromising my own liberties). I know many people, conservatives and liberals, who don't care at all about the environment. They believe that we should be allowed to do anything that makes our lives better, even if it means making the world as a whole worse, or they just don't think that the environment needs protecting. Also, illegal drug usage includes marijuana usage, and clearly there are a lot of people who support marijuana usage. Personally I believe that all drugs should be legalized and controlled. If you want to ruin your life then that's your problem.
