Fuel [2]

I sent out a replacement car to a customer who had trouble with his car, claiming all sorts of lights came on. The tow truck driver spent 3 hours getting to said customer.

When the driver dropped off the car, he noticed that the only trouble with the previous car was that the fuel light was on. The customer claims "I've never seen that light before, so I didn't know what it was."

The thing is, in the car he had, it's shaped like a fuel pump.
