DIY Fuel Injector Cleaning & Repair
This is the end result of a few hours of work and $60 because I didn't have
a 1/4" NPT tap in any of my kits. I could have done this for less-than
$40. The BG products were donated to the cause.
The REASON you want to use 20 PSI is precisely because of how peak-hold
type injectors work. The injector signal sends a 4v spike to open a
peak-hold type injector quickly, then maintains its open condition with
only 1 volt. Really, it's a current thing and there's a longer
explanation, but that's it in a nutshell. When you put the injector in its
operating pressure, it takes more than a AA battery to open it, but you
don't want to sustain that much current with a momentary switch and your
expensive injectors. This isn't in the video because this warning wouldn't
be as clear. Unless you can simulate the injector pulse precisely, don't
try it. 1.5v is enough to open it below its operating pressure. If you
open it and THEN apply pressure, you can flow as much pressure as you can
throw at it.
I don't discourage anyone from getting their injectors professionally
cleaned and balanced, but in my case, I didn't feel that was necessary.
In my first video, I thanked the seller for these injectors and happy to
know I got a great deal on high quality parts. My gratitude is even
greater because I had problems with them. It gave me an opportunity to
help others troubleshoot these kinds of problems when purchasing used
parts. A different idiot might have blamed the seller for peddling crap,
demanding their money back... but that would only be because they didn't
even know what they were looking at.
This particular idiot knows what high quality parts RC injectors are and
how to clean 'em. $250 + $60 still means I saved about $150 on a brand new
set. We all benefit because I bought these and I'm grateful! Let the good

In this video I detail some quick tests and some not-so-quick fixes.
A dirty or stuck injector is not usually a fatal problem for the part. You
can clean injectors yourself with a little ingenuity, or use an injector
cleaning service. With the method I'm using, you won't get a sheet that
measures how much fluid is flowing, but if you use the right solvent you
can at least remove whatever is blocking it so that it can flow like it did
when it was new.
So the journey begins.
Ultrasonic Fuel Injector Cleaning Bench
Carbon Zapp Ultrasonic Fuel Injector Cleaning Bench. Ultrasonic cleaning of
injectors is the only way to guarantee the injectors are clinically clean
and back to their original condition. When reconditioning injectors with a
testing and flow bench results can be quantified and noted directly by eye
rather than guessing at results of chemical cleaning of and injectors

Yamaha F115 Outboard - Fuel Injector Cleaning
This set of injectors came from an engine that would not run at all and
were sent to us for cleaning and testing. The F115 is prone to injector
problems and we service several sets of these each month.
The first two clips show the injectors being tested under revs and again
under static load. You can clearly see that injectors I and III are
The second two clips show the injectors undergoing the same two tests but
after two hours of ultrasonic cleaning. At this stage the injectors are
good enough for the engine to run to an acceptable standard. We cleaned
the injectors for a further hour and found during subsequent testing that
this was sufficient to enable the injectors to flow and function 'as new'.
This service fixed our customer's problem for £57 including insured return
