I noticed that I was using very little biodiesel/diesel from the factory installed fuel tank. Hence, I was carrying around 14 gallons of Biodiesel/diesel and only using 2 gallons a month. I was only using this fuel to heat up the car and purge the injectors for shut down and this didn't take very much. So I figured it would make more sense to put a small tank in the trunk for the biodiesel/diesel, remove the large WVO tank, and use the factory installed tank for the WVO. This would give me much more room in the trunk and allow me to put the spare tire back inside the tire well. In the pictures, you can see the new biodiesel/diesel tank in the corner with a 7 gallon capacity. Note that I had to switch the fuel lines at the factory installed tank so that the WVO went to the heated fuel lines. I can also now use the factory fuel guage in the dash to see how much WVO is left, where before I had to keep checking the trunk. The pictures below show the new setup, notice that you can see the WVO filter, fuel lines, and heater hoses in the left corner of the trunk.

A fuel tank that I got off of Ebay, I think it was originally used to store animal feed. I wanted something that was easier to fill than my first try at a WVO fuel tank (see bottom of page). So I got this. It holds about 15 gallons. I simply drilled holes in the top for the fuel lines and used a high strength elastic band to hold it in place. It fits down inside the spare tire well, I simply placed the tire off to the side of the trunk.

To fill the container, I simply release the band which holds the two parts together and slide the top over. Then I can pour in the WVO from my 5 gallon containers or from fuel distribution drums (see my biodiesel page).

I didn’t want to spend a lot of money on a fuel tank because I didn’t know if the theory of the WVO would work and also because I wanted to keep costs down to allow for car repairs. I bought 7 gallon water jugs at WalMart for around $7 each. I very rarely shop at WalMart because I hate the things this corporation does, but I there was no other place in Kings Bay, Georgia to buy this sort of thing. I hooked the two tanks together using a siphon.

I made the fuel line bigger than was needed to help with the cold weather viscosity flow. These tanks are not heated. I have run the car in 11 degree F. weather with no problems with canola oil. This oil stays liquid down to very low temperature, hence I see no need to heat my tank.

The clear hose in the picture is the refueling hose, the copper pipe is where the siphon is to maintain a constant level between the two tanks. The clear hose also shows the oil level in the tanks.
