c5 1999 fuel pump
my gas gauge is stuck at zero guys, and i believe i need to replace my fuel pumps however the fuel pumps for early c5 corvette are discontinue so i was wondering if I bought the 2000-2004 fuel pump for my corvette will it read my gas?

You need to get the correct pump. The '00-'04 will not work on a '99. With that said, just because your gauge is at zero doesn't necessarily means you need a new pump. If you have gas in the car, and it starts and runs, I would try running a few bottles of Techron through your tank. This is a known solution to the fuel gauge issue that you describe. Be aware it may take several bottles (one per fill-up) before it starts to work.

The number of bottles of Techron needed varies from case to case. You can usually find BOGO deals for Techron at a lot of auto parts stores. As such, I would start by buying 2 20oz bottles and start with that. I don't know how much you drive, so I don't know how long it will take you to go through that. However, that's a good start. It may take a good bit more than that though (or it may not). It's hard to say.
If you do end up needing a new pump, I wasn't aware that they were that hard to find. When I tried googling 1999 Corvette fuel pump, I got lots of hits.

They have the complete setup for driver’s side tank, don’t see the sending unit and jet pump for passenger tank.
Are you trying to find the compete setup for passenger side tank?
Did you try Techron yet?

Another driver side complete pump and sending unit for even less $$ searching under “fuel pump” category.
The first link was search under “fuel pump and housing assembly”
