"I need some tips on making a 3 tank sytem work. Most things I have read here involve letting the oil settle and heating/filtering it. Is this possible while driving, if I have a seperate dirty tank?

I want to use standard types of filters as I will be travelling in mexico and want something very common in older busses and trucks. How many filters and what types will I need? Is it possible to use hydraulic filters?

I am thinking of using the coolant hoses to heat the tanks, possibly along with an electric heater. Do I have to cut open my tanks, or is it possible to feed the hoses in?

I am also looking at putting my veggie oil line inside the coolant line that heats the tank. Does anyone know where I can find the fittings for this?

As for WVO collection, what type of pump is best/cheapest? Do I really need to shell out $200-$300. And does anyone have experience collecting WVO in cold climes?
