Although, as others have said the straps will ground the tank and
sender (as was original on Crosley), they aren't always reliable due
to age, dirt and corrosion.
It is MUCH better to add a separate grounding wire, under one of the
sender screws to a screw or bolt on the frame. Naturally, you will
want to sand/grind the frame down to bright, shiny metal where you
attach the wire and don't paint it until AFTER the connection has
My 2 cents, no change required.

I've put a new sender in the tank already. I've painted both the
tank and the straps also. I'm still on the original 6V positive
ground system as well if that matters.
I've got the one wire for the post on the sender all set to go.
How to I properly "ground" the tank shell to the body? Should
there be a wire? Or did the straps originally ground the tank?
I could add a wire from the body to a screw on the sender also if
need be... just unsure that is necessary.
I've seen some other older cars that have a rivet in the
cardboard/asphalt insulating gasket that sometimes goes between
the straps and the tank for grounding, but I don't have any
originals to inspect for the Crosley. Checked the manuals, but I
don't see this detailed.
Thanks for you insights.
