In a fluid delivery system for delivering a fluid into an individual's body, a leak detection system indicates that the fluid has leaked outside a normal fluid path of the fluid delivery system, such as near an infusion site or a fluid-filled reservoir. Preferably, the leak detection system includes a chemical positioned near the infusion site that reacts with preservatives in the leaking fluid to generate a highly visible, brightly colored, chemical complex. Alternatively, mechanical, electro-optical, electrochemical, electrical or other chemical systems may be used to detect the presence of fluid that is leaking near the infusion site. Further, the leak detection systems may be used to detect the presence of fluid that is leaking from or near other locations within the fluid delivery system, such as on or near a fluid-filled reservoir, or a flexible tube coupled between the reservoir and the infusion site.
