I picked a 03 5.3 last week from the junk yard. I got the motor installed and the injector connects are same as my bosh 60lb injectors. Did they change injector connects in 03 or are these flex fuel injectors.

Here are some pic's

wow nobody knows.

 

Those are flex fuel injectors. I think around 33lbs if memory serves me right. Same as I have in my dads truck.

 

Thanks kyle. Kind what I was think but just wanted to sees op had to say.
