I want to add a 50 to 100 gallon tank in the bed of my truck for running pre-filtered SVO. I will be using the "start on dino/ switch to grease when hot, switch back to purge" method.
Here are a handful of questions on a variety of related topics. I know I don't know my full engine system so please be kind!
Going off the Greasel Nomad system, I'm thinking of building tank the width of the bed, 2' high (4" above the side of the bed), 16" deep (from cab toward bumper), with a 2" chamber at the bottom for running the coolant. I'll create an open chamber (essentially a wall) on the far lefthand side of the tank for valves, filters, etc. I don't want anything sticking out in the bed to get knocked off by cargo. Therefore, the finished unit will be 64" wide but the fuel tank will be more like 52" wide.
Tank material: What should the tank be made of? Regular steel would be heavier but cheaper. I already have black Line-X on my bed. The tank should be painted the same. This will help pick up some heat from the sun. Alum. would be lighter but hard to hold paint. I specialize in treating stainless steel (passivation, electropolishing) so I could make it highly polished but talk about pricey! Any dissimilar metal concerns? I'm leaning toward steel.
Internal Tank Corrosion: I'll be using Evans non-water coolant so corrosion in the heater chamber shouldn't be a problem. The oil itself should keep the main chamber free of rust. Ideas?
Veggie pre-filtering: I'm in the chemical business so heating and filtering the raw waste veggie oil is no big deal. I'll gather the used veggie in a 55 gallon drum with pump in the back of my truck. Then, I'll bring it in the shop for "polishing." I have some 275 gallon totes, Parker filter carts, heaters, etc. for doing pretty good filtration. I hopefully be able to pump pretty good oil into my tank (in the bed).
Veggie filtering: I am wanting to install a Dahl filter for the regular fuel system. What about filtering the veggie? I'm thinking it needs to be 5 micron or better. What about a heated filter like the Vormax? Racor? Also, do I still send both liquids through the stock filter mounted on top of the engine?
Fuel pump: sucking a viscous liquid like heated grease seems like it would be murder on a lift pump. I've heard of a lot of pump failures. What about using a pump to get the grease from the tank toward the engine. But, where to introduce it? Before the lift pump? Between the lift pump and the high pressure pump? What type of pump? Standard electric fuel pump? Demand pump like a Shurflo?
3-way valve vs. 6-way valve. I've noticed some kits come with a six-way valve. I assume this is for return fuel lines so it goes back to the respective fuel tanks. But, doesn't the 2002 fuel dead head? I've been considering a return regulator but this is beyond my budget for now. A return line so there is no pooling of veggie in the heads sure sounds good. It would make for a complete purge of the system before shutdown.
Air in lines: I'm going to do the harpoon/pre-pump mod soon. What about preventing air in the grease line? Baffles in the veggie tank?
These are my bigger questions for now. I have learned a lot from the folks here. Thanks for any more help you can provide.

One thing to be aware of when adding tanks to the bed is weight. Keep in mind that 100gal of veggie probably weighs in around 800-900lbs...often overlooked. This gets to be important especially if you're towing anything.
On the fuel pump question, a lot of guys that run 6.9l's like mine remove the lift pump and put a plate over the opening, and install a Holly Red electric pump, which is probably what I'll do if I EVER get to this project...LOL

Ah yes... based on specific gravity of .92 SVO (a bit heavier than biodiesel) it weighs almost 7.7 pounds per gallon. That makes 60 gallons 460 pounds of fuel. A 60 gallon aluminum transfer tank/toolbox from Northern Tool weighs 135 pounds without pump, filter, etc. Add about 7 gallons of coolant, plus the difference between alum. and steel and we are bumping 700#'s for sure. My truck sits just right with 1200 pounds in the bed so I won't mind that much weight.
You are right... on anything less than a PSD it is a big concern.

Not so much to do with PSD...more of a note to folks that are running 1/2 or 3/4 ton trucks, and don't realize that an extra tank that size is their WHOLE payload. So they can't tow, and have to throw the wife, kids, AND dog out.

Here are some ideas about the tank. I want to wrap the top rear corner with some angle iron so that it becomes a solid brace. This way shifting loads won't damage the tank. I'll add some tie down loops as well. I want to make sure the entire tank is attached to the side rails somehow. I don't want to mess up the rubber top rail pad.
I have 18" from the cab back to the wheelwell. But, I don't want to eat up too much cargo room. How tall would you build the tank? The Greasel tank is 24" tall, I believe. That is 4" above the side of the truck.
Any other ideas on the tank design.

Something to keep in mind is that if you add 100G tank to the bed that you most likely will not have a full fuel load in both stock tanks, so in actuality you are adding 60G worth of weight to the rig?

I'm not sure I agree...
I think most folks that add an aux tank are going to fill everything up...stock tanks, aux tank...and STILL put a bunch of stuff in the bed, and it all adds up quickly to an overloaded vehicle. People just aren't used to counting the weight of fuel...

On most accounts I would agree with you Lob, but this guy is talking about adding 100 gallons of SVO to the bed, thats the reason I said he most likely wont have both stock tanks full of diesel as well. Would kind of defeat the purpose of converting to SVO IMHO. [img]/ubbthreads/images/graemlins/shrug.gif[/img] I can see having 5 to 10 gallons on board for starts and stops, but not a full system.

Why go through all this bother?? Just run transestrified biodiesel in your regular fuel tank. I'm not a big fan of straight/waste veggie. It has its own polution & performance issues, that I think are addressed by using bio-d. If you don't want to mess with making your own, buy a commercial grade & help support the industry.

I have considered going with biodiesel. I own a small chemical company and have all the right equipment. But, I HATE caustic. (I'm also a safety instructor). I'm used to working with blends that don't change from batch to batch. Add X pounds of ingredient A, X pounds of ingredient B, etc. The idea that you have to run tritation on each batch doesn't appeal to me at all.
I have also done filtration for hydraulic service and find that much easier.
As a designer of chemicals and processes, I want to apply the same attention to detail on my veggie system as my regular work. This is true whether I cook my biodiesel or filter & heat it with the two-tank system.
I'm not completely opposed to the transesterfication process. Sell me on it a little.
Thanks for your input.
