Your setup looks impressive but pretty hard to justify by someone who only goes through about 60 gallons of off-road Diesel a year and hardly any gasoline.
Good used gravity fed tanks out there for reasonable prices.Diesel fuel lasts a long time with proper additives 2 years or more..
Same here. When the gas light comes on, I put the 5gal can on the seat and use the pump to fill. It takes the whole 5 gallons with maybe a gallon or so to spare. I'm fine using just 5 at a time. So much easier than holding and using whatever slow crappy fill spout the gov wants me to use at the particular time.
My M has similar fuel tank placement, but it is still easier to pump than to lift and pour.
I second the HF battery powered pump. I just put the 5 gal can on the backhoe seat and the pump does the rest. It’ll pump 5 gal in just a couple of minutes and the pump only costs about $7 on sale, $9 if it’s not on sale. Even if you have to replace it every season or two it’s a bargain. I’ve used mine to move about 50 gal of fuel so far and it’s still on its first set of two D-cell batteries. If this one ever dies I’ll buy two more so I’ll have one for backup. I’ll never be without one of these pumps again.
I got worried last year about my 8 year old diesel in the belly tank of the generator. Checked it. Looked good, but started to use it for the tractor. I just pump out 20 gallons, 2 gallons at a time for the tractor, and then replenish from containers bought at the service station.
