just pulled out my injectors to change o-rings to rule out a leaky injector,and come to find out i have 7 injectors all the same and one is different...they are all 19lb but one is obviously different...i have had these same injectors for like 3 years now with no apparent problems, but could this be an issue??????

 

do you know what injector it is? color numbers anything? could have been a replacement just different color

 

it is the same color just seems like it is a little bit bigger...

 

at the bottom of injector where the fuel flows to intake it is different, like there is a needle and my other ones are not like that

 

if it makes you feel better buy one stock one and replace it.

 

I ran 24lb injectors for awhile and not a single one was the same lol. I doubt its an issue, id say as long as there all the same color for the 19lb. you should be fine.
