A fluid delivery apparatus provides for controlled delivery of fluids into a fluid system. The fluid delivery apparatus can allow a defined volume of fluid to be delivered to the fluid system cleanly, minimizing fluid waste and spillage. The fluid delivery apparatus can provide a mechanical advantage allowing the fluid to be delivered easily and efficiently to a pressurized fluid system. The apparatus can have a piston and handle arrangement that can reduce wear of the apparatus.
