fuel heater!!

helo all, i running pennut oil with aditives (so u don't have to do the converson kit) and i need to heat this stuff in the fall and winter. so my thoughts were to use the fuel bowl heater (hints it alredy there) but how would i controle this thing? i know i can put a relay and a switch to turn it on and off, but i don't want to over haet the fuel. so is there any kind of thermostat i can put on the fuel line to turn it on and off??

Not sure about the bowl heater kit but I run my truck on grease also and I heat the lines by running coolant lines with the fuel line. I also have a heat exchanger under the hood and in between the heat exchanger and bowl I have a thermometer with a gauge in the dash.

I think you'll need more than just a fuel bowl heater. You're going to have to address the tank, lines, and pump, otherwise you'll end up with 1 cup of liquid fuel and 30 gallons of gelled fuel.

You should also consider the fuel that will be in the fuel rails next to the injectors, which I don't think the block heater will do enough to keep from gelling. Don't most of the guys running WVO or similar switch to dino diesel before they shut down to prevent gelled fuel in the rails?

But he's running it without a kit, as factory as it gets...

Yes, but that's the reason for the kits. The only options I know of are either start cutting it with diesel to find the gel point, or switch to dino for the winter.

Maybe go ask the guys down in the biodiesel section. They would know for sure.

Is it the peanut oil, or your additives that are keeping it from gelling? What brand of additive are you using?

My concerns would be the thicker fuel putting too much of a strain on the fuel pump and causing it to go out, or having the fuel that sits in the injector rails getting thick and causing problems with your injectors.

well it's not gel'n just thicker when cold, and it works ok in the cold, just tring two make it a little thiner by heating. as far as the additves go it's thined down with k-1, gas, kleen desiel, and some thing to keep it from qagulating.(can't remember the name). the peanut oil is not as thick as u think after mixing, yes a little thiker than desiel fuel but not bad.

Where do you get that much peanut oil to make it worth the cost?

Behind any restaurant, I have yet to have a owner tell me I cant take there WVO.

As far as making it just a little bit thinner I would definitely suggest just running some coolant lines with your fuel line. That the only heat source I have for my 100 gallon grease tank in the bed of my truck and it works great.

Just cut into the coolant lines before they go into the heater core, run the lines under your truck and insulate them with the fuel line touching the rubber coolant lines and run it back to the heater. Cheap and easy, I will post pictures of mine when I get home tonight.
