Fuel injector cleaning

I discovered an injector cleaning vid here on youtube, so I thought I'd make one specifically for XJ owners and the popular 703 swap.

DIY Fuel Injector Cleaning & Repair
This is the end result of a few hours of work and $60 because I didn't have a 1/4" NPT tap in any of my kits. I could have done this for less-than $40. The BG products were donated to the cause. Tech info: The REASON you want to use 20 PSI is precisely because of how peak-hold type injectors work. The injector signal sends a 4v spike to open a peak-hold type injector quickly, then maintains its open condition with only 1 volt. Really, it's a current thing and there's a longer explanation, but that's it in a nutshell. When you put the injector in its operating pressure, it takes more than a AA battery to open it, but you don't want to sustain that much current with a momentary switch and your expensive injectors. This isn't in the video because this warning wouldn't be as clear. Unless you can simulate the injector pulse precisely, don't try it. 1.5v is enough to open it below its operating pressure. If you open it and THEN apply pressure, you can flow as much pressure as you can throw at it. I don't discourage anyone from getting their injectors professionally cleaned and balanced, but in my case, I didn't feel that was necessary. In my first video, I thanked the seller for these injectors and happy to know I got a great deal on high quality parts. My gratitude is even greater because I had problems with them. It gave me an opportunity to help others troubleshoot these kinds of problems when purchasing used parts. A different idiot might have blamed the seller for peddling crap, demanding their money back... but that would only be because they didn't even know what they were looking at. This particular idiot knows what high quality parts RC injectors are and how to clean 'em. $250 + $60 still means I saved about $150 on a brand new set. We all benefit because I bought these and I'm grateful! Let the good times roll.
