I was wondering if anyone knew information on fuel injectors...?

I have a 98 T/A and from what I read the 1999 to 2000 LS1 engines came from the factory with smaller 26.3 lbs/hr injectors (GM part numbers 12456154 and 12555894). I assume the 98 is no different in regards to factory fuel ratings.

Now do i have to change out the fuel pump if i go to the larger 50psi injectors?

From what I have read the 99-00 specs are 28.2 lbs/hr (3.55 gps) at 58 psi (400 kPa) - This is factory LS1 and LS6 fuel pressure.

Recommendations welcome....

Thanks for any information you guys could give.
