I don't think the FPR being a GM or aftermarket matters, GM ones failed too. NAPA and Autozone use the IDENTICAL part (I bought both, and took the NAPA one back, saved me a ton of cash....)

As for injectors, you can just use any injector that will fit, just need to tune for it. IF you don't wanna tune for it, you need to use Cadillac 4.5L/4.9L, TPI 305, or 99-00 LS1 injectors (still need to look at the 97-98 LS1 injectors to confirm). The LS6 injectors (which are used on 01-up LS1's), and LT1 are larger yet (24 lb/hr @3 bar, 28.8 @ 4 bar). The L98 are in the middle, they are 22 lb/hr @ 3 bar and around 25.5 @ 4 bar). The L29 is a 4 bar fuel system.

Yes, if you have the opportunity, get the stock L29 injectors out and toss them in the trash, witchhunter said they are not even cleanable with his equipment.
