Since the Bronco is new to you, it never hurts to verify (either through looking, or just using it) that the hoses and lever are actually still in the stock locations.
What I'm getting at is that it's very easy for a PO to have replaced the hoses over the years and attached them to the wrong fittings on the valve.
It's also easy enough to pull the small screw holding the lever to the valve, and putting it in any position.
These two scenarios are actually quite rare for some reason, but it does happen.
Maybe the dreaded PO's (previous owners) are actually being careful for once when they mess with gas?
Have fun with your new rig.
Oh, and to post images directly to the site from your computer you have to be a contributor (13 bucks a year), or use another online image hosting site like SuperMotors or another of the many that perform that function and then linking that image to your post.
I didn't see a link above either, but since someone viewed your image successfully, I'm guessing I just missed something.
