Fuel injector cleaning machines - worth the money ?

[NoReverseYukon]

Has anyone bought/used one of these ? I do use Techron Complete Fuel System Cleaner, but the reverse-flush capability of these machines has me thinking buying one might be a good idea.

Good investment or a waste of money ???

Since you omitted / forgot price of injector cleaning machine,

Price of injector cleaning machine

Number of injectors to be cleaned

The more injectors this machine will clean, the better the return on investment.

I suppose if you run a shop and can "sell" the service and the associated work and issue's that may come along with it.
like customers complaining that the issue persist's, o-ring replacement, gaskets and gasket issue's (intake leaks), bent high pressure fuel rails, clip and harness repairs (stuff gets brittle over time) etc, etc.

This isn't a business venture purchase. This one costs $250 +/-. And I am only asking those who have previously bought/used to chime in on whether it actually does what it claims it can.

Wonder if it checks metering, too, so injectors could be matched as sets.

Dave's Auto (on YouTube) near Salt Lake City uses a commercial injector tester in-house.

I made one with a used Tahoe fuel pump & an old fuel rail from a 1980's TPI system

They are quite useful for cleaning & checking for consistent flow rates

The reason I made it was because of the high failure rate of new injectors these days, not uncommon for a set of 8 to have 2 stuck open or closed; stuck open will flood that cylinder the moment the fuel pump comes on

For the price that seems like a good investment, my homemade one is a bit clumsy and I use paint cups to measure flow volume; that little system looks much easier to use

It does have those graduated cylinders.. The 'volume detection' I am assuming..
Sure looks nice for some peace of mind or for eliminating faulty injectors if running sub-optimally.

Wow! 2 out of 8 stuck! That's depressing to hear..
Nice work on the custom setup!
