i just cleared 20 acres of south florida swamp and had to rent several pieces of heavy equipment. they sucked a lot of fuel. i was not too prepared. i just bought road fuel and siphoned it in via 15 gal chemical tanks from the tailgate of my truck. i will have a second phase of land clearing soon. i think i will get a big fiberglass marine tank and put in the back of the truck and buy some kind of manual hand pump. i can get 50 gallon tanks for $150. i don't need one of those permanent tanks in the back of my truck. does this sound like a good alternative? thanks for any input. scott.
