fuel injector question (crack) help asap.
 

So im about to throw my injectors back in but one of them has a small crack at the plastic piece after the o-ring where the fuel is delivered (not that clips in the end that goes into the intake). Is this going to hurt anything?

Given that they did not manufacture them with cracks my gut tells me that any cracks would be bad...

lol well the one i had saw was only a hairline crack and it didn't even span the whole way from the top to the bottom of the tip.

They make replacements from napa but they are $4 and change each, which isn't bad but they come with o-rings and i just bought 16 new o-rings, i went back and found a few injectors had a small crack and one was bad, i think i may just get new injectors, I think they are stock injectors with over 150k on them, they deserve retired.
