I dont know bout the rest of you but diesel goes up every day round here. Now its at 2.65/ gallon. With that price I am thinking vegetable would pay for its self in a month or two very easily.

Heres my idea:
Since our trucks are already equipped with two tanks and the switching solenoid why couldnt I just get a couple inline fuel heaters and a good filter to run on that restaraunt oil that they throw away out back in the dumpster?
I have been reading about kits and all they have are a heater, a filter, some hose and a tank and our IDIs are perfect canidates for free fuel.

I dont know anymore than anybody else so advice is very welcome.
