where can i find for sure what size injectors my truk has. its a 99 silverado with a 4.8 L
i just put in a 5.3 L but used my intake and injectors.

i was told 99 is different from all other years?????

 

Dude if I'm not mistaken I think they are 20lbs. per hour.

 

and the newer ones are 24 lb??

 

21.763701

 

24 OR ACTUALLY 25 I THINK. I GOT THE 25LB. DELPHI SPRAYERS IN MINE.

 

24s are in a 5.3...not sure about the 4.8 however..id imagine the exact same..jsut changed in the tune

for reading sake....if you ever plan to upgrade..the 8.1L truck motors run 31-32 pound injectors that are a direct plug in for out harnass's..most other fuel injectors like SVO's and LSx injectors use a different connector...so 8.1L ones are the way to go!

 

From the info that I've gathered here, the 99's are different and flow less than 00 and up...I believe the numbers are 21lb vs. 24.7lb or something like that. The 4.8 and 5.3 use the same injectors.
