I'd like to convert my 87 6.2 Sub to veggie oil. Anybody running one of the systems on the market? Two tanks?

I`m afraid to.Playin`wait and see.

Got deezel? I bet there's someone nearby that has already done the conversion. Usually on a Mercedes or Volks. My only concern is who's kit to use.

Confused? Me too... The VORMAX filter seems to be the one. Then the fuel tank issue. $$$ to build a small deezel, and where to put it? Behind rocker? Behind right rear wheel well? And fill directly from restaurant to tank thru VORMAX filter. Thereby not storing oil at home. A pain...

if you make biodiesel out of the veggie oil instead of using straight veggie oil you can put the biodiesel in any diesel engine or furnace etc.
then you don't have to do any mods to the truck.

Yeah, but also enjoy the novelty of running spring roll oil...

a guy came into work yesterday doing that exact same thing, complete veggie oil from local restaraunts. He starts it and runs for a few minutes on regular diesel then switches to veggie once it has heated up. He is running a line from the coolant back to the veggie oil tank to heat it up.
Didn't go into too many details but I got the main idea behind what he is doing.
