After hours of analyzing and years or experience plus a very few seconds of brilliance,, found a really cheap way of re-filling tanks with fuel.. at NO COST!! Really works if you are able to lift a full plastic juice container without strain or pain..... available at most food stores...
Rinsed out and dried a former 1 or 2 litre plastic juice container instead of throwing it into land fill or recycle bin, placed a funnel to fit into opening, placed both containers on ground and lifted the larger fuel container, ( often 20 litres and quite easily lifted if you're in reasonably physical shape,) filled the smaller one, capped it so as not to spill, lifted the smaller one onto tractor - or whatever implement - filling opening which already has another smaller funnel if you've prepared correctly,remove the cap, tilt the container until empty, Repeat until said tank is almost full. No fuel gauge? Have a clean wooden rod and tip into tank til hits bottom. Check where fuel line visible.. Do not scrape and DO NOT use a metal one to avoid sparks.... Even having to step up higher, still quite safe and simple....
Helped by Einstein's comment :
"It takes an unusual mind to analyze (or see) the obvious!!" Thanks to Albert!
And especially in these times critical to keep a sense of humour... And thanks to Chaplin!!
