My fuel gauge is a motometer set up, unfortunatly also rare and money when they do turn up.
To be honest they are not that accurate and regular peeks inside the tank is regular practice. I tend to keep the tank topped up anyway as it reduses the amount of corrossion as it keeps the air/moisture away from the inside of the tank.
You can get repro fuel measuring sticks now also (they were an original dealer option back then)
