Cool set up but how much fuel do you get out of the tank being the pickup tube looks about 1/2 way down the tank?
The 2 ports on the sider are connected to tubes that curve around to the bottom of the tank. They stop about 1 inch off the bottom of the tank. I'm guessing this is the ports the tractor uses to supply fuel. I could have used the ports on ends but I was afraid it would suck up dirt and trash. I think they were intended to be used as a drain.
145 gallons: Have you had any problems with placarding and/or DOT hazardous transport tickets or anything like that? I've heard the lmit is 119 gallons or so depending on the state. I plan to "trailerize" my 135 gallon farm fuel diesel tank and that's the only thing I worry about.
