Did this happen on a turn? What exactly was the car doing when it died on you?

I'm not familiar with the Regina system, but it could be a couple of things. If it is the fuel sender (in tank arm) and pre-pump you want to examine the hose that runs from teh pre-pump to the sender's metal hose. What happens is that the hose from the pre-pump wears out over time and develops a hole. Said hole allows air to be sucked into the fuel line when the gas level in the tank drops below the level of the hole. I think the FAQ talks about this problem in detail. You need to pull the sender assembly, inspect the hose, and replace it if necessary.

A dead pre-pump won't cause this problem, but you should check before you pull the sender to see if it's dead and replace it if it is. Pop the gas cap and put your ear to the hole. If you hear a whine from the tank that's the pre-pump working. If you hear nothing or don't THINK you hear anything the pre-pump is dead. It's REALLY obvious, so if you don't think you hear it it's dead (I didn't realize hjow noisy it was until I installed a new good one). All a dead pre-pump will do will strain the main pump (by forcing it to work alone), making it slightly louder and shortening it's lifespan.
