I need to make a plan to get the Monarks installed.

Where I used to work We reserved the Ultra Sonic cleaning Tank mainly for used Direct Injection Nozzles because picking out the Holes to clean them could enlarge them and at the same time was time consuming.
Used IDI Injector Nozzles could go the US Cleaning Tank but We normally used Carburator Dip on them to disolve the Carbon.
In fact both types of Injectors were taken apart and went into the Carburator Dip and were then hosed of with Solvent.
Any exterior Carbon was wire wheeld off with a very fine wire whee. (but not the tip where the Holes are).
So Nozzles going into the Ultra Sonic Tank were already pretty well cleaned. Unless there was some unusal problem the Injector Bodies did not go into that Tank.
Unless the passages inside of the upper Injector Body are rusted inside there is no abosolute need to put them in the Ultra Sonic Tank.
What you really need to get out of the passages on the Injector are Lapping Compound or if you use abrasive Paper to lap with. That can be done with Brake or Carburator Cleaner and compressed Air.
With compressed Air it is best to have a Filter and at the very least something to separate the Water out of the Air.
I can remember getting ready to assemble an Injector dipping the Parts in Diesel Fuel and blowing it out or off with Air only to shoot a lot of Moisture into it because someone had not drained the Water Separators.
It just causes you some more cleaning time but it is better to think about it before it happens.
But, I had the littley HF Jewlery type US Cleaning Tank for at least 4 years and I used it more for cleaning other parts then Injectors. Limited of course by the size.
I have had the Larger HF one for at least 2 years and the Larger size helps alot.
One of the last things I used it for is I threw My original Ignition Lock Tumbler inside and gave it a good cleaning.
I think if a Person buys one of those Tanks they will find themselves putting all kinds of parts into it.
For those who plan to re-use the good Stock Bosch Nozzles. Even if you can come up with the right Sized Music Wire to clean out the tiny drilled passages in the Pintle tip that will not get all the Carbon out. But, an Ultra Sonic Cleaning Tank has I believe will.
