There are in place (Non Dismantle) fuel injection cleaning kits available. The set up is as follows; Disconnect the fuel lines to the injection fuel log on the supply and return ports. Cap the return port and attach the injector cleaning equipment. Start the engine and let runs until the cleaning agent runs out. Re attach connections to normal and your done. I used this process quite a bit back in the 90's and it worked well.
Where might I get something like this these days? Is there a brand name or something to look for online?
