Does anyone know which chemicals a professional fuel injector cleaning machine uses? I have a small setup that will allow me to connect my side-feed injectors to a pressurized system and fire the injectors in order to view/verify a good consistent spray pattern, before installing the fuel injectors back into the fuel rail. I have a lot of injectors to test/clean.
Most the information I found pertains to injector cleaners as a fuel additive, rather than a direct cleaner. I'm interested in using a good cleaner, that will not damage the o-rings on the injectors (if possible). I'm also looking for something affordable to purchase locally, in 5 gallons or less (ideally by the gallon).
I looked at Toluene, as it seems to be an ingredient in many other cleaners, but it looks like it could be tough on o-rings, unless the o-rings are made of the newer Viton Extreme (rather than A, B, or F). I don't yet know what the material of my o-rings are, though I suppose I could use old o-rings in the fuel injector cleaning machine, before installing new ones for use.
I can use straight cleaning fluid, or I could mix it with fuel (to avoid the volume needed in the small tank to source the pump, etc.).
Does anyone have any experience with the chemicals used in the professional cleaning machines?
