Gas gauge not working? I think I fixed it.

I'm not sure a Jerry can is the answer, LOL

"Back in" the first gas crunch in the 70's, I actually put an outboard tank in the trunk of my 70RR. It was securely strapped into eyebolts through the trunk floor, and vented out externally. Had an electric pump that would simply dump the contents into the main.

"Back then" the dammed service stations would leave their signs rotating and lights on, but they'd be closed and out of gas.

There was at least TWICE I finally pulled into a working station with both pumps rattling for something.

Seriously, here's a couple of things I thought...........

Small tank tucked up in the left quarter, with a "Y" in the flller would fill both. Electric pump on a toggle to transfer

Or, small tank up in the trunk. You could construct this so that the filler would go into the reserve, but the outlet into the main (filler) would come up inside the reserve........so the reserve would fill, then spill over into the main. That way you could fill both from one filler outside.

Again, a pump could either dump into the main, or electric selector valve, etc.
