Adjusting fuel pressure C3, C4 Corvette with Crossfire injection This will be the same on the F body

Thanks but it would be nice to see some details such as what the adjustment tool looks like, where exactly the adjustment screw is, and where the fuel gauge is located.

Thanks Larsonhomeinspection for your comment. To see the tool up close and what it is adjusting look at the rebuild video and to see how I made the pressure gauge there is a video on that here are the links. ua-cam.com/video/AF_clVhgXI0/v-deo.html ua-cam.com/video/uoE18P-ZiEg/v-deo.html I hope this helps!

@84c4corvetteguy5 ok thank you. I did watch the rebuild one. Will have to rewatch it!

Do I only have to adjust the one carb to get the right fuel pressure, or is it a combination of both?

[@84c4corvetteguy5]

There is only one adjustment. The fuel flows from the front or passenger side TBI through a accumulator spring ass. (NOT A REGULATOR) then to the crossover tube to the drivers side TBI where it goes through the pressure regulator before returning back to the tank. So there is only one restriction in the system and that is on the drivers side TBI. I applied a picture of the fuel system to the title I hope this helps.
