As most of you know, the next best way the clean your injectors next to pulling them and sending them off for the ultrasonic process is to have pressurized cleaner fed into the fuel rail. In this process, the fuel pump is disabled and the car runs off the cleaner directly. The unfortunate part of all this is the kits from NAPA are ~ $400.00 (3M also sell a similar product line).
Anyway, it has always pissed me off that they charge so much for this kit knowing the actual cost is probably 20. Then it occured to me ... I wonder if the threaded connection on top of the can is the same as that found on AC coolant cans? If so, then I could simply use the valve and gauge on my AC kit, cut the quick disconnect off, and then make use of a barbed fitting to splice the proper schrader fitting on for the fuel rail.
Off to NAPA ... guy puts the can on the counter ... I get a can of AC coolant off the shelf and put it on the counter next to the cleaner ... @#$%@#$% .... the threads are different ... these guys are not stupid, they want you to buy their overpriced kit (and if I were them I would have done the exact same thing!!!) ... Well at this point it is getting personal ... I buy the cleaner (just under $13.00) anyway determined to figure a way out to make this work!
The following pictures speak for themselves, I am not going to bore you with the details other than: I had to use a dremel to grind the stem down in order to get the cleaner to flow & make sure you clean all parts before using ..no chips in the injectors please. Also, make sure you check for leaks everywhere.
This works, I noticed a definate difference, I did forget to clamp the return line to the fuel tank so the car only ran for ~ 5 to 7 minutes instead of the 15 to 20 ... I will be getting another can!
P.S. Go to Harbor Freight and buy their fuel pump test kit ... for ~ 13.00 you get the gauge shown and lots of fittings!
