Couple choices, skinny tank along side the drive shaft.

Interior tanks are popular, not my fave.

Ditch the spare and put it on the roof or get a swing out tire carrier and build a two tank system, maybe 20% diesel and the other half 80% veggie.

I have swung back to bio as I have heard many conflicting reports on the veggie, do a search there was some talk recently on this subject.

hey rob,

the spare is already on the rear bumper and i was thinking of the 2nd tank in its place.

ive read the posts about veggie problems, and i am by no means an expert, but people have been running veggie oil for a long time with out any problems and i think that if your system is set up right and you are very particular about the oil you use, you should be able to run veggie with no side effects to your engine.

so what are your experinces with veggie oil?
have you had any issues?
is your spare tank sitting where the spare tire was?
how long were you running veggie?
do you have any pics of your set up?

cheers,

I think your in an area where an external tank will never be warm enough. I think for your veg tank it needs to be inside. Otherwise you will be using too much enegry trying to heat it underneath.

Someone in the south may have no issues, but up north we need it internal.

I would make two internal tanks tee'd together. With them side saddled over the rear wheels. One on each side. Made out of aluminum diamondplate.

Or just use one larger tank. Forget anything bigger than 50-70 liters, otherwise you will never see it get hot enough to flow. In those temps.

Even the internal tanks of mine would have a 120v heater to plug in night in the winter. Like a barrel heater.

External tanks would need some wicked insulation. Otherwise that thick crap will Gel in the below -30 weather.

Your system has to reflect where you live. in Alaska your choices get more limited.

I've had mine inside, on the roof rack and on a swing out tire rack, but ultimately ended up just getting a wide low profile tank and leaving it in the rear cargo area.

Handling was bad with it on the roof rack, way too much lean in the corners. Inconvenient and looked crappy on the back of the vehicle.

Make sure you get a tank with baffles so the slosh doesn't bother you no matter where you put it. My baffleless tank sucks air and looses its prime when wheeling over rough terrain.

thanks guys,

it gets cold here but not that cold. i wouldnt run veggie in the winter anyways.
i think im going to have someone fab one out of aluminium and put it where the spare tire was. that way it doesnt take up any more cargo space. maybe ill have to get air bags to help with the extra weight too.

for those running veggie, how long, (miles, months or years) have you been doing it? what works and what doesnt?
what kind of set up do you have?
ive been reading up on some of the main websites, greasel, frybrid, greasecar and a couple others, id like to hear from some cruiser heads.

thanks again,

Even if you built a under the truck tank it somehow would need some intuslation and if the two tanks were built together there would have to be a small air space between the tanks.

Condensation in the tank would be a problem for the diesel side when heated and cooled.

Still on the fence, about which way to go, getting pushed towards the bio but still like the veggie after driving a truck with it.

The system this fellow used was a on demand system, not recirculating, so he would flash up the engine and a small glow type plug would kick in and keep the veggie hot until the coolant was up to operating temp.


I was unaware this could be done, worked great.

I have a Greasel conversion on my F350 and I think I will do the same with my pig when it is done. It has an external heated tank that worked fine below zero. I have been very happy with the kit but frybrid has made many advances in their system since I purchased mine a year and a half ago.
But I must say that there is a huge learning curve...but nothing that cannot be figured out if you are mechanically inclined.
Good Luck-

Is it important TO YOU to use 100% VEG OIL? Many people prefer the simplicity of a single tank system using up to 50% veg-oil / diesel mix. All you add is a heat exchanger to heat the fuel. Simple, cost effective, trouble free.

yes i want to run 100% veggie oil when possible. up here it wont be much, we only have about 80 miles of road. but i will be moving in the next few years and will be able to (hopefully) run straight veggie oil. there are few good welders and fabbers here and i think we can figure it out. if you guys havent read "from the fryer to the fuel tank" and are into the biodiesel/veggie oil thing you should check it out. its a pretty informative book.
and veggie will work in cold climates. you just have build your system with that in mind.
