OTC’s recommended process runs your engine with a strong cleaning solvent like their 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 30000 psi! The full-size cap makes adding solvents easy and spill proof. A fuel injection application manual and fluid transfer hose are included.
