Okay so this update can either be seen as ghetto as f**k or awesome. You can all decide haha.
But basically, I wanted to clean out my injectors properly! The redex crap is exactly that and I think the only way to clean them properly is to leave them in an ultrasonic bath.
I researched into it whilst on my lunch breaks at work and saw that simply leaving them in an ultrasonic bath wouldn't do that much in comparison to with them being pulsed like they would be in a real life situation. So I had a search, and bought an ultra sonic cleaning bath!

It had loads of great reviews online so went for that one.
I had a spare injector from when I replaced mine a month ago as it was giving me hassle.

I then bought a petrol injector pulser.

However this gave me a bit of a problem (known to me already). It only worked on the car battery as in 12v, which wasn't ideal as everytime i'd want to do this i'd have to be in stupidly close proximity to my battery in the freezing cold = not comfortable at all.

So a bit of googling returned results that I could actually use a spare computer PSU to get a 12V feed by simply crimping the yellow wires together.

So I did just that, crimping the blacks together for the earth and the yellows for the 12V. I can actually use the reds for another feed, think it might be 5v or something

I can then (crudely) hook up the injector tester to my PSU and voila, it powers up. I do intend on making it more secure in the future as now it is simply crocodile clipped onto the wires of the PSU as shown.

I then needed to test the injector using the pulser however I obviously need to get some pressure behind the injector. This was really just to see how it was looking prior to cleaning. As said, it was giving me some issues that's why I changed it. I then found some pipe that it would fit into snugly!

I then hooked up a squeezy bottle to the other end, again this was air tight so my intentions were to fill the pipe with fluid through the blue bit and screw the bottle on and then squeeze that to apply pressure to the injector.

I then hooked up the terminals to the injector

And now I can squeeze the bottle whilst pulsing the injector.

When doing this test I noticed that the injector only appeared to be spraying out of two parts and hitting the glass in two clear parts, much like a car windscreen washer. I couldn't get a picture of this as I don't have three hands.
I then filled the bath with near boiling water and all purpose cleaner (actually got some proper cleaner waiting for me to collect at work)

I then turned the pulser to constantly pulse and turned the bath on for 480 seconds.

I could see the dirt coming off, not as much as what I expected however.
Hooking up the injector back to my homebrew pressure tester lead to some interesting results. I thought I had completely broken it as it wasn't spraying any fluid...
or what I thought anyway, I just couldn't see anything?? So I got my torch shining on the injector and it turned out it was actually spraying but instead of clear droplets that I could see before it was more of a mist and that's why I couldn't see it! I also noticed that instead of it spraying out of two nozzles like before it was actually spraying out of all 4 of the micro holes in the end.
This is proven that it worked as the injector should ideally be spraying in a mist rather than like a hose pipe like it was before!
Glad my little ghetto testing and cleaning rig worked
Going to be doing my actual ones at the weekend with the proper cleaning fluid.
Thanks for reading, it's been a long one haha
