C5 Fuel pump
My 2001 fuel pump has died . What are some good replacement options that are drop in and not universal that requires a lot of work? Looking for upgrade as I have about 600 hp

AFAIK, I have an OEM fuel pump and its good enough for a 427 making 617hp@crank. I know I have never replaced it......

and the factory fuel pump is not supporting either on its own. You may think you have the factory fuel pump....

With my cam only C5Z I'm getting to the limit on stock injectors. With heads/E85 planned this winter, new injectors and 340 pump are going in (ignore the E85 portion requiring a bigger pump). Curious how you are making that much HP and still on stock injectors/pump.
