Ok...so if there ain’t fuel blowing out the boosters and vents, your gauge is garbage. That’s all that can be. You can’t have that much fuel pressure and expect it to not push fuel out every hole it can find.
This ^^^ is getting to actually to actually determining the truth.
Here's what you (VonCamp) need to do to check this out.
Engine off, look at the carb bowls. Each one will have either a clear fuel level window, or a plug.
If its a big window, fuel should be near the middle.
If its a small plug, near the bottom - shake the car, you'll see it. If its brass plug witha slot, remove it. Fuel should be right at the bottom.
If its close, then start the car and check again. They should stay the same as when stopped.
Be careful. Take all the obvious precaustions working with open fuel if using sight plugs that can spill out.
