You can use one of your two existing tanks for vegetable oil or add one of our 4 sizes of Universal Truck Tanks or less expensive tanks from other vendors: http://www.plantdrive.com/html/faq.html#29

The Installation Manual does not ship with the product. Rather, we send it to you in PDF format when we send you a shipping confirmation. We also tell you where to download Adobe Acrobat, in either Windows or Mac versions, in case you don't have it, so that you can open the PDF attachment.

Not included are coolant or fuel hose or hose clamps. The manual tells you where to buy them at local auto parts stores or online. We do this to keeps the cost of the kit down - hose is bulky and expensive to ship. Also when we shipped hose, years ago, we had to include enough for a worst-case scenario; that is, long wheelbase trucks with an 8' bed and an extended cab need more hose than a shorter truck,and customers would either want to return unused hose, feel badly about taking it to landfill or were loath to add it to the other junk in their garage. And of course they'd paid for that unneeded hose. As for hoseclamps: we give you a phone # for McMaster-Carr and the part number for their finest hoseclamps, and if you order before 5 and you live west of the Mississippi you'll have your clamps by 10 AM the next morning, 10 AM the following day if you're east of the Mississippi. You'll pay less than if we included them in the kit and you can easily order more if you add a heating component like a HotFox or HotPlate later The cost for an average passenger car for hose and clamps will be under $150, and for a truck, under $200.

We tell you how to assemble a hose-on-hose assembly. You'll bundle the synthetic rubber fuel lines with the synthetic rubber coolant lines so that the hot coolant exchanges it's heat with the fuel in an adjacent line. Hose-on-hose is easier to run that hose-in-hose but more importantly, you avoid the risk of losing the coolant due to an imperfectly installed compression fitting, or a compression fitting that loosens over time, with the very real possibility that your engine will overheat, resulting in a blown head gasket, cracked or warped head, cracked block or all of the above.

A NOTE ON TANKS:

We do not include tanks with these kits as many people do not need in-tank heat (see above) and our kits are not dependent on in-tank heat to work. Therefore, a wide range of tank options is possible. Customers have installed the Hotfox, if needed, in almost any conceivable tank. Some vehicles have two tanks. One can certainly be used if you wish, for SVO. We recommend the tank be removed, cleaned, install the Hotfox while removed, and then reinstalled. Others have used surplus tanks, recycled tanks, Tidy Tanks, Northern Tool truck bed tanks, tanks with tool boxes as part of them, plastic marine tanks, RCI aluminum tanks from summitracing.com, dune buggy tanks from jegs.com, etc.

Basically, with our kit you are not locked into buying a tank from us and you have a wide price range, size, and mounting locations to choose from.

If you do get one from us, it will be thicker aluminum and a stronger, better tank than others sell, with a method of filling that is convenient, and your spare tire will stay in the car, typically, in the spare tire well. Any tank you use must be properly installed, mounted solidly, vented, etc.

CAN YOU INSTALL THIS KIT? If you are a capable and careful "backyard mechanic". If not, get help from a friend who is, or from a professional mechanic who is willing to read our instructions and work with you/us, or get one of our dealers to install it - see our Dealer page. (In that case, have the DEALER order your kit for you, it costs you the same either way and they get their dealer discount.)
