Any one keep track of injector part numbers and the factory calibration of flow numbers??? or does any one know were I can find the info along with actual flow numbers?

For example I have a 2000 silverado with a 5.3L
Has Injector #25323974
GMs Injector Flow Rate shows 24.801938 LBS per hour in the factory calibration.

Also Have a 2001 silverado HD with 6.0L
Has Injector #25317628
GMs Injector Flow Rate shows 25.235972 LBS per hour in the factory calibration.

When you look up the Injectors they all have Different Actuall flow numbers.

 

Where are you looking up the actual flow numbers?

 

Gooled differnet injector numbers and different sites had different info...

Been fighting lean codes on a truck that was pieced back together. I looked up the injector number and I believe thats were my issue lays. It has part number 25320287 injectors from an unknown engine likely a 4.8 or 5.3 because of the vaceum port on back of manifold. according to one site there said to be early 99 into 2000 injectors with around 21lb of actual flow. according to some info I read, 25320288 would be the injector I need for a 2000 model 2500 6.0 those are said to be around 24lb injectors of actual flow.

Not sure because I wasn't able to find consistant data of actual PSI flowed and Liquid used to flow test. be nice If I had 1 of each injector that I could send to 1 company and have them flowed at the same PSI on the same equipment.

 

Might want to call John at FIC, very knowledgeable guy on the subject...
