Its another name for a mobile fuel cell. We called them NT’s when they were mounted on a trailer.
Good advice, keeping your bulk tank as full as possible as a partially full tank in a climate with large swings in ambient temperature can and will sweat inside (get condensation on the inner walls, just like a cold glass of beer sweats on the inside of the glass above the liquid and it drips down into the liquid (in the case of diesel) and with diesel collects on the bottom of the tank and when you draw diesel from the tank, it gets sucked up with the fuel. Why I have my pickup tube for the pump a couple inches off the tank bottom btw as I cannot refill the tank with a little bit because my diesel supplier has a minimum150 gallon fill or they impose a surcharge. I never fill mine completely full either as expansion of cold fuel when it expands can cause it to expand out of the tank and spill out and NEVER weld on any fuel tank, empty or even cleaned inside, you'll never get the vapor out and it will explode. We are professional welders here (I own a machine and fab shop and we NEVER weld on any enclosed tank, fuel or otherwise. Been many 'accidents' happen and welder killed by doing that, well documented also). That includes ANY fuel or solvent tanks. If the tank don't have an existing bung on it, buy or rent a NEW one, no exceptions. Finally, I'm not at all keen on the vapor collectors as fuel vaporized much sooner than water and the internal condensate inside the tank will drop into the fuel, long before it will vaporize and collect in the dessicant collector. It will drop into the fuel and collect in the bottom of the tank. Why I have a bung with a valve at the bottom of mine and drain it off monthly and my tank is sitting slightly off level with the drain bung at the lowest point and I still have a filter on the pump head and still use a Racor style filter on my tractors. Never too many filters. Like I said, an ounce of cure is worth a pound of foolishness. Never had a water or debris in fuel issue except one time and that cost me a grand in replacement parts and I did the grunt work myself and had to have all my injectors rebuilt as well. That was years ago when parts were actually reasonably priced. Your choice, actually anyone's choice. Pay me now or cry later.
You can buy or rent a bulk tank from almost every fuel supplier and they rent cheap. Your 'transfer tank' is small compared to the one I have in my farm truck. Mine is diamond plate aluminum and it's a 175 gallon and it's for sale btw. It has a manual diaphragm pump on it as well and it's polished aluminum with hold down tabs for hard mounting in the bed. I don't use it anymore as my tractors get really good fuel 'mileage' so I can get home if they need filled an if not, a plastic 5 gallon fuel can gets me back 100% of the time. We didn't build it, I bought it and it's an EPA certified tank as well. I paid around a grand for it new, I want 500 for it and you pick it up or I can ship it for an additional cost. It's mint, no dent's no leaks. I'm in southern Michigan but I can ship it anywhere for the ship price. Has a lockable pressure venting fill cap and the pump is lockable as well. If anyone is interested you can shoot me an email at sales@flipmeisters.com and I'll reply and I guarantee it's pristine or I'll give you your money back.
