I have a 180L tank on Grumble (which runs on unleaded when I can't get LPG). My Genny also runs on unleaded...
I was mulling over a way of fitting a takeoff - either from the tank, or just after the (external) pump by means of a solonoid valve and key operated switch (to avoid accidental turning on), fed to an outlet pipe to fill the tank on the genny (obviously with an in-line filter).
The Ebby heater already has a similar setup...
Can anyone please attempt to talk me out of thinking about this further - p'raps to prevent me from taking it to the 'rough drawings on the notepad' stage?
