Product details:

OTC's recommended process runs your engine with a strong cleaning solvent, like OTC's Pro Inject-R Kleen (sold separately), which is introduced directly into the fuel rail where maximum benefit is achieved. The debris that is loosened or dissolved is then combusted and ultimately removed through the vehicle's exhaust system. The hydraulic cylinder is machined from stainless steel, has a 22 oz. capacity, and is able to handle pressures up to 30,000 psi! The full size cap makes adding solvents easy and spill proof. A fuel injection application manual and fluid transfer hose are included.
