Theory on why senders read full during a dry test vs actual use.
We're adjusting the senders and assuming the float will reach the top of the tank.
We're forgetting about air space above the fuel and the fact that the float won't touch the top of the tank in operation.
If someone is in this process, try setting the float for an inch gap from the top of the tank.
Why do you believe there is air space at the top of the tank? IF the filler neck on say a 68-70 Charger is full of fuel, how could there be an air space ?
I'll refer to my earlier post #3227987 for my thoughts
I'm beginning to think it may have something to do with the buoyancy of the float, possibly coupled with today's fuels or weight of the arm
