I have no idea how much water it takes to make a car pump, but I can tell you that it’s a lot of water, and it’s a lot of work. Most car pumps are made of plastic, which is why they can take about a day of your time to complete. I’m not sure if this is the case in the US, but it seems to be the case in Australia.
I have no idea how much water it takes to make a pump, but I have no doubt that it’s a lot of water. A pump is made up of a pump motor, pump impeller, pump housing, and pump rod. It takes a lot of water to make a pump, so to make one that you can actually pump water into a car, you’d have to make a lot of water.
