Puma and Cowgirl,
Here is the premise: a couple of men are behind the theft of diesel fuel from farms spread out all over the state. One of the men has an old service truck with a fuel tank. Remember that when this tank truck is driving down the road it has to be DOT legal with a driver who has a CDL-B with haz-mat, tank, and air brake endorsement. Otherwise, if a cop stops it, it will be put out of service and parked. When the farmer is sleeping, the thief drives onto the farmer's land (having the fuel stored next to a road is one possibility) and steals the fuel. You need a pump. The pump could be on the truck, either driven off the electrical system or a PTO. I'd go with an electric pump as it is quieter. You need hard suction hoses to avoid collapse. You could get an electrical pump that is not attached to the truck like a sump pump. Flow rate is going to be very important here. At 10 gpm (gallons per minute), it would take fifty minutes to empty a 500 gallon tank. At 100 gpm, you reduce this down to 5 minutes. Then, he takes it back to his place - and eventually it is delivered to another farmer who is willing to buy the questionable fuel for a discount. There's no way to identify the fuel as stolen, so this would easily be done. The two thieves are splitting the money.
If you're willing, when I get to the details (like exactly how the fuel is transferred into the service truck), I would love to have you explain how it would be done.
As far as the dye: so a farmer can add the dye to his fuel without any problem? I got into one site that made it sound as if you had to have permission from a government agency to add dye to diesel fuel. Is this right? The dye is added due to road tax. Diesel for over-the-road vehicles pay a significant road tax. Off-road vehicles like tractors do not have to pay this tax. At weight stations, trucks can be "dipped" to see whether they are using off-road fuel. Fines are massive. If the dipped fuel shows a trace of the dye, then you get to write a big check to the government. The dye is added at the refinery. Reality is you don't want the dye in the fuel. If you can get some fuel oil or diesel without the dye, you can put it in your truck, as a savings of something like $0.50 per gallon.
And another question: if you got the fuel on your pants, would the red dye stain them? (So someone might mistake the stain for something else?) And...would the smell of the fuel be so strong, it would be obvious to anyone nearby that they were smelling fuel? (I need it to NOT smell!) Fuel smells. If your house is heated by fuel oil (which is very similar to diesel), you've smelled it. It will get into your clothes and you will smell. The dye will not stain your clothes as it is a very low concentration.
Thanks for any additional help. If you're willing to be a source for me, I will mention you in my acknowledgements and send you a copy of the book when it comes out in November. If you need more, feel free to PM me.
