Well I may have finally screwed up "trolling the thrift stores." This morning I drug home an Airtex EFI cleaning kit, which I payed "dearly" for (25 bucks), and it turns out might have been "moreso" that I first thought. I've Googled this all sorts of ways and cannot find a thing on it. Worse, Airtex didn't even bother to mention in their destructions.........what the part no. is for the mysterious pressurized cleaner. I have not taken the regulator down to O'Really's? or N(o)APA yet, to see if anything they have will screw into it.

Evidently, the Chines........I mean Airtex is not very proud of this thing

It uses a pressurized aerosol. I have no idea how many types there might be. I know I used to have a can here which I "adapted" LMAO. The thread on the can was same as the rear of a BNC RF connector. I cut, soldered, adapted, and used it "once" on my Ranger. it was wasted effort. I "forgot" about the return path to the tank. As soon as I pressurized the rail, all the "stuff" fed back into the tank!!!

LOL............You have NO idea how difficult it is finding a photo of an original BNC, as the market has become so polluted with copies and pirates and "crimp on" mostly junk

In the photo below the connector on the left. The inside thread of the rear of the shell fits the can I had "some time ago." I managed to solder the empty shell to a fitting and adapted it to my needs. This system is "similar"

Damn Del,sold Airtex product since 91,never seen Airtex make one of those. I would venture it's a budget version of the same era 3 M " professional " cleaner kits. Carquest/Napa also had similar systems. They work great,when used properly.
 
Looks like the run the fuel rail off of the can setup Castle chemicals sold under
the "Fireball" moniker long ago.There have been many others along the way. We had a Justice
Brothers setup at my previous shop,and until recently a BG setup at our dealership,both are a
"fill the can & use reg'd shop air"type that use a misting nozzle in the air inlet near the TB.
Frankly,the BG stuff was mostly acetone w a few proprietary extras added,but
it worked.We've needed to de-carbon a number of the newer direct inj. turbo engines,it's
sickening how fast these things carbon up!!One of the reasons the 2.0L boxer shared by suby
and toyota for the BRZ/FR-S siblings have direct AND port injection.

I have absolutely thought about building that very thing in place of the pressurized can. What I find interesting is that they run this can of cleaner THROUGH the supplied regulator. Whatever they have "in the can" must not hurt the regulator internals
 
straight acetone. Heck, the cheaters (uh, me in the near future) run a 1:3 acetone/gas mix to pass the NOx test, wonder if water injection would do the same? (cool the combustion chamber so 2500F NOx formation is lowered) Yeah, I think there is a 60 psi rated cylinder that goes with that. fill cylinder with acetone or $10 injector cleaner, pressurize to 60psi, then attach to schreader valve...pull fuel pump relay and somehow defeat the return system, open flow valve and start car until it stalls. What do they charge for this service nowadays?
 

No idea "in car." When I swapped engines in the 86 Ranger, the injectors were dirty from sitting. I don't recall there's a local guy with a cleaning machine setup. I think he charged me about a hundred.
