1990 Z28...how can i figure out what size injectors i have?? i know stocks were 19lb and 22 lb, but i am not sure what size mine are since the car was cjanged to a 350 from 305, I think they are 19lb, how can u tell though? color?numbers?
thanks!!

 

I think the 19's are yellow and 22 blue not sure,trying to remember from my 92z.If not pull out and see if there is any id numbers of there.Thats your best bet.Then you can call a local gm dealer w/ the part number and go from there.

 

I really need help on this one : ( mine are blueish green..dirty blue...

 

i just hope they are 19lb, because they will explain to me why i am running 15.09

 

Take one out and get the P/N, then Post it for a ID.
