Injector numbers.
 

--------------------------------------------------------------------------------

Hey guys I decided to change a bad injector. the old injector is numbered 25317628 and has 2 holes in the bottom. The new injector is 25323974 and has 4 holes in the bottom. Should I use it ?
this is on a 5.3 if that helps.

Call some of the dealerships and tell them what numbers youve got because I went throught the whole number game a while back because they started making new ones with a different numbers. Just check around they should cross reference it for ya. Call a couple of GM dealerships like ------>>>>>SDPC
