Good way to check and clean injectors

Jul 29, 2004 9 Replies

I cleaned injectors a couple times by using my mighty vac pump hooke dup to the rail end of the injector, create a vacuum.



Hook the injector up to a light 5v AC adaptor, and put the engine end of the injector in a bowl with carb cleaner.



The 5V ac makes the injector pulsate and the carb cleaner gets sucked through it. You will be amazed how much crap comes out of the injector. U can also check the spraypatern like that.



Using that stuff as we speak. We'll see what the mystery stuff will do. >

how do you check a spray pattern if it is pulling the liquid backwards thru the injector?

Sorry, I forgot to mention, U use presurized fuel or carb cleaner. I build a canister with a pressure regulator, works pretty good

clean without a lot of expense.

Sucking explosive fumes into a mighty vac with arcing brushes may not be a good idea.

That is good! I was picturing something like a shop vac. :)

Oh. One of those. I don't think I ever did pay any attention to the name of it. Mine looks much the same & black plastic. Thanks Geoff.
