Cracked injector

Took my injectors out today to clean. Basically hooked a 9v to it while spraying carb clean. They were pretty grimes and the one test drive so far has been a big improvement, especially third and fourth. I did notice however the end ceramic tip on one injector was cracked all around. Not loose or anything and its probly been like that for a while but Im definately replacing it. Close to stock car so no need for bigger injectors. So should I relace all injectors? What is stock psi, 19? Best brand for money? Thinking motor craft. Is it just the 170000 miles that caused this? Cuz they are original

That part that gets cracked is called a Pintle cap. You can replace it.

There is more to servicing a fuel injector than meets the eye. There is also a small fuel filter inside of the injector that is replaceable.
You can buy the replacement parts at Mrinjector.com.

Just rebuild them and make sure they are clean like you seem to have already.

Yep, way cheaper doing it that way and you probably already got them clean with the 9V and the cleaner. You will probably be amazed at how much better the car runs. Changing to rebuilt/new injectors has cured everything from a rough idle and lean/rich issues on former cars I've owned not to mention going from shot injectors to fresh will give you a bit of a power bump depending on how bad the old ones were.

They are really simple mechanically so as long as you spray something through them while holding a 9v to it, or maybe a ultrasonic parts cleaner or whatever it's called. And to rebuild them there's some good vids on YouTube

I usually just rebuild them but if you want to run cleaner through them you rig up a tube with some HEET or whatever to the injector, get a couple blade connectors with leads on them and touch them to a 9V and watch the spray pattern. If it mists nicely then move onto the next one.

even better. i already have new o rings on them all, its just the filter and the other part that's new to me. Am i tapping the 9 volt in pulses for individual sprays? or will touching and holding the connection to the battery cause a constant spray?
