I just filled in all the information for this and it deleted it.

Fuel injector cleaning adapter. Forwards and backwards. 1/4" OD vinyl tubing. Custom fittings.

You can power the injector with 12v, a power transistor, and an Arduino. If you need the code please leave a comment. Pulse anywhere from 0.5 to 8 ms on and off for 20 to 100 ms. I put the on duration on a potentiometer and did every 50 ms.

The fittings work good for hand pressurizing with a syringe, I'm sure they could do a little more but not 50 bar.

I used isopropyl alcohol as a flush agent.

Update May 2025: Did not seem to help with a lazy injector. I don't think I want to mess with flushing at this point, if it ends up being an electrical or mechanical issue. Although buying a singular injector is not desired due to the possibility of batch differences or failure, it will be my solution due to cost and rarity of F injectors. These engines AFAIK do not adjust per injector, only timing angle per cylinder.
