Modern Vespa

Didn't really mean to do this 20 miles from home!
Made it to the SHELL station for some good stuff....



Might have had another 40 miles of gas in there.....might have.
The trip gauge is only good if you were completely full the last time!

O.S.

On the instrument of my scooter, when the reserve starts it automatically resets the partial and counts the residual distance up to zero.
Do it this way ... bring back a liter of gasoline in a container; when the last line turns off and going at a constant speed, mark the miles until you stay still. You will know how much you can do with the reserve, then you refuel with the small container until you reach a petrol station.

Thanks.
But not keen on running any engine out of gas.
O.S.

Yeah, I don't need to know the exact, full limits of my tank. I know when the light comes on, I should find a place to fill up within a few miles. And it's bad for the injectors to fully run out, right?

... right ... but it will happen if you don't know exactly how many miles you can still do, so it would take a way to prevent the problem ...
Nothing will happen to the injector, but the HP fuel pump could be damaged if it was turned over.

45 years on the road - never run out of gas. Thanks for your concern - but, I got this.

O.S.

I don't like to stop, so I run mine to empty on almost every tank.

Once, I put 2.65 gallons into a 2.5 gallon tank, so the Vespa GT has a larger tank than they claim.

In well over 1000 fill ups, I have never run out.

My MV Agusta 125 from 1956 has a tank with two fuel taps, and when one ends, the other opens ... never left me too. On some Piaggio models a software should be placed which together with the partial speedometer automatically resets and marks the remaining autonomy. Write an email to everyone and send it to Piaggio ... you don't know but they could listen to you.

Yep, best never to run your fuel tank dry ever. Bad for the pump and bad for the filter. The pump gets hot if you run it dry, and the pump seal goes dry (bad). Plus everything gets hot well before it runs dry too. Best to keep it emersed in in nice cool fuel

We need an idea like this:

Acerbis has tanks that you mount to the forks of off-road motorcycles. They have a syphon tube that connects to the fuel tank vent pipe. As the fuel tank empties, it draws fuel from the fork tank into the main tank. I am sure that one could fashion a similar tank to connect to the Vespa Tank vent...
