Anyone have their own machine for this? I know some have probably built homebuilt volume testers, but this thing is cheap enough that I might not even bother, and it has the ultrasonic cleaner attached. 

I'm weary that the price is so low that the entire thing is junk. Any thoughts?

That's REALLY cheap.  Wow.

Google has a lot of negative feedback and scam warnings about supplygb.

In reply to SkinnyG (Forum Supporter) :

That's a fair point, but there are similar (looking) machines for $250 ish all over the place, and I guess the question still stands. 

If it's a useful tool, I'd be interested. If it's junk, I'd rather send my money to someone who will actually clean fuel injectors.

The other ones are all over the place, from probably more reputable stores.

I am tempted to get one for myself, but they don't have a consistent level of "glowing" reviews.  Some were DOA, some died early one, some were fine.  Probably cheaper to buy one than to source the hardware to make your own, and even to fix it - how hard can it be?

I want one.

I don't think I want one this cheap/sketchy.

I started planning this out in my head a little more. I happen to have just bought a spare intake/tb/fuel rail/sensors/wiring/injectors that would fit my jaguar (it was an eBay impulse bid, but no one else bid so I won for 99cents and then paid $40 shipping haha), so I've got lots of the hardware needed handy. To build my own, I'd need:

  1. Some sort of solvent tank
  2. A fuel pump
  3. A fitler is a good idea
  4. A rail and pressure regulator, adjustable would be nice but not necessary
  5. Wiring and a control box to fire the injectors
  6. Some graduated cylinders
  7. Fuel lines, clamps, fittings, etc
  8. A structure to hold it all as I don't have 17 hands

So even just in my own materials it's looking like $5+$40+$10+$40+$65+$15+$10 (about $200, of which I personally already own about half of) to build something, and then it would have a couple pretty major limitations. First is the injector controller I can find for $65 only does 2 at a time. Workable but annoying. The second major limitation is that I'd have to keep dumping the graduated cylinders manually back into the tank, and that would make longer test cycles impossible.

Finally, the $300ish machines also come with a heated ultrasonic cleaning tub, so that would be another $75-$100 for me to buy separately. All in all, it is starting to sound like me doing all this work to diy a tool isn't really worth the few dollars saved by doing so.

That said, I still feel like this $300ish tool is the harbor freight version of a fuel injector cleaner. Are there better ones out there (even if higher priced) that I should consider as well?
