With the current fuel prices, I've been seriously considering running veggie oil. Of course I live in the cold half the year so I can't swap just to veggie oil. So I was thinking of converting the truck the run dual fuel. I have another fuel tank that I can mount beside the current one, I can't imagine it would be that hard.
I made a quick plan. Basically run it on diesel until the truck has warmed up. Then switch to veggie oil. I can easily tie into my rear heater lines and run a small liquid/liquid heat exchanger. I can also route my exhaust to hug the veggie oil tank, possibly allowing the oil to heat up that way, maybe even running copper tubing in coils inside the tank. I found some cheap duel fuel tank selectors that are electric, so it's as simple as flipping a switch.
What are you're guy's opinions?
The truck is an 86' 4runner too.
