Home made ultra-sonic FI cleaner Options

[Mark Henry]

I had an old electric tool engraver lying around. I hose clamped the tip to nut and another hose clamp, and then I clamped it to a small Tupperware condiment container. I then put an injector in it and added FI cleaner till it just covered the injector.
Put on the top and plugged it in, it works great. I have cleaned a couple of injectors now including one with a seized pintle (sp?) that has now freed up.

Check out the jewelry cleaner at Wal-mart, it's basically the same thing. They don't cost that much $30-40 US I think. Engravers are about $12.

I just did it this way because I had the tool engraver, a lot of guys do and I now have two tools for the price of one.
Not to mention the fact that I'm sometimes just a tad cheap.

I don't think putting it on the injector would be a good idea, plus you have to keep the engraver dry, being an electrical device and all.

Go through all your injectors with dirty fluid then dump it, put in some clean fluid and do them again for a bit.
I’ve had one old skanky injector that won’t free up. Also the FI cleaning fluid will not remove certain types of grease (etc.) so I cleaned and scrubbed the injector before I put it in, still you should see all the crap coming off of them. I'm running each injector for over an hour.

Also the noise, I’m going to put mine in a box and put it outside.
