I realized that the 14 cylinder BMW radial would be mighty thirsty,so I added a fuel tank from a Truck to the engine test caboose Cool! 
Nice add-on Eugene. [Y]

Thanks!
UhOh!
How many miles per gallon are we gonna get? Interesting, Eugene!
I was going to add fuel lines but they might interfere when I have to change the battery in the tool box .
