OTC's Professional Master Fuel Injection Kit (P/N 6550PRO) is a full coverage tool set developed to accommodate nearly every fuel injection system application on most domestic and foreign engine platforms 1988 to present. The set's quick connect adapters use Schrader valves to prevent fuel/solvent spray, and every seal used is made of Viton rubber to resist swelling or cracking, even when exposed to ethanol blend fuels. Included are OTC fuel injection adapters; 0-100 psi analog pressure gauge with manifold for accurate pressure reading and basic flow testing; hose assemblies; a variety of seals, fuel lines and clamps; and an application guide and laminated card showing color images of components with part numbers for quick reference. The blow molded case with its removable lid allows for convenient storage and easy access to components, yet closes tightly for safe transport of the kit.
