Anyone have experience with the OTC 7448A Fuel Injection Cleaner tool? This thing is purpose-built to connect directly to the fuel rail (or just at the damper with an adapter) where it bypasses the fuel system and delivers fuel injector solvent under pressure (either their propriety brew, Inject-R-Kleen, or any similar product; eg: BG 44K, Chevron Techron, etc). The thing requires an air compressor to work. You hook-up shop air to the canister and dial-in the rail pressure for your vehicle. You then disable your fuel pump. fill the canister with solvent and hook up the delivery hose to your car's fuel rail via a quick-connect adapter. Open the valve, start the engine, and let it run until the canister is emptied (indicated by a stalled engine). Repeat with another can, or schedule another session twice a year or so. Cool huh? I'm not a fan of gas-additive fuel injector cleaners, nor am I keen on the onerous chore of removing each injector for direct cleaning. At just over a measly hundred bucks for the 7448A (plus another twenty or so for the adapter), this seems like a reasonable regular maintenance tool for the home shop. Anyone care to vouch for the OTC 7448A tool?
