Oh, and not matter what you end up doing, test the new sending unit with your gauge BEFORE you install it permanently!
While it's out is when you can easily tweak and tune it so that it reads where you want it to read on the gauge.
The Bronco gauges are finicky and complaint-prone enough, without having to add that to the reasons to hate your gas gauge!
Forgot to say something about your selector valve in the pic. The PO sure did a nice job of trying to hide it's actual function didn't they! Can barely see the lever in all that carpet, much less the bezel/plate with the identifications on it.
Glad you even saw it!
I suppose this is the time to bring up the old "pull-for-heat" question too.

Hey, it's not too early. Is it?
Just messin' with 'ya there. It's a common issue with new owners not familiar with all the controls, so if you're not sure what I mean by that, then this is the perfect time to bring it up.
Even though it has nothing at all to do with gas tanks.
