Oh wow so it is set up like Dean said. Hmmmm my '79 had the electric setup but it was a 3 port valve instead of the later 5 port. Took me a minute to find one. So I'm guessing the gauge doesn't switch if there's a manual valve or how does that work?Nope. There is a manual valve on the driver's floor board by the seat. And then the filler neck is supposed to be in the wheel well on the driver's side.
