I can never fill my tank completely?

[TLyttle]

I'm working on my third fuel gauge sender, and it's going too, ie, something is wrong when one has 260k and the gauge registers the full 8 bars. Also, I don't fill past the auto shutoff, as discussed here before, and the damage to the carbon capture system. 500k (300 miles) to the tank is fine, why push one's luck?

What's the failure mode of the senders? The only vehicle I have ever had one fail on was a Subaru, and with that one the sender had a dead spot from 3/4 to 1/2, where the gauge would just drop to zero through that range. On that car it happened after I left the car sitting without driving it for about 6 months.
