Wow! These responses are great,thanks for all the help so far. So here is an update.
Bulbs for brake lights are the same for tail and bulbs are fine. Rear blinkers work fine as well. Checked the only fuse panel I could find and there was no fuse I could find. So will test ground at bulb?
I checked and yes there are 2 tanks. Front tank and rear tank. The rear tank is main and front is alt. When idle or off flipping the switch does nothing that I can see change or hear.
Not aure what grey tank is made of but will post a pic.
I have two tanks with a toggle switch. When I switch it, the only thing that changes is the fuel level gauge if they both aren't full. I don't hear or see anything else.
Well I put $20 and both tanks ran one of them to wear said empty switched the toggle and it still showed empty. So I would think the guage would change?
It could be that the fuel sending unit is bad. If you can't get a replacement, try this guy - he repaired mine.
If you know one gauge and tank works, then fill that one up full. Then run on the other one (which shouldn't be full) until it runs out or you reach 100 miles. If it runs out before 100 miles, then you are most likely running on the second tank but the sending unit is bad.
If you reach 100 miles, then go to a station and try filling up the first tank again. If it is still full, then you were running off the second tank and the sending unit is bad. If you can fill it, then it is not switching to the second tank.
That's the way I worked out my tanks - it took some trial and error.
Oh, and if you have anyone work on your fuel system make sure they tag your tanks to the original connections. I had mine done and the toggle got reversed so when I filled up my first tank and thought I was running on it, I was actually running on the second...
