Injector/Fuel rail cleaning frequency request
Injector/Fuel rail cleaning frequency request I've read that crap builds up in the rails & can block injector openings on fuel systems where the return is looped back @ the tank w/single line fuel rail feed. So, how often should the rails & injectors be cleaned & injectors flow tested?
I was told not to run stuff through the injectors alot because the cleaners are so thin that they can eat away where the injectors are put together by the tip and then a leaky injector will be next....but never have experienced that yet.
