DIY Cleaning for Perkins 4.108 Injectors

[SailnParadise]

I'm looking for an economical way of cleaning my injectors. I have identified them as the reason my engine isn't starting. I am in the Miami area right now and the lowest quote I get is $140/each. I would like to find a cheaper way. What is possible? Or does anyone know a place that is sub $100 per injector in the area?

I considered buying an ultrasonic cleaner off amazon and letting them sit in a cleaning solution. Anyone ever tried this?

I gave away 4 to these guys last summer, might be a good place to check.
