Alrighty then. Let me first say thank you to any and all that reply with sensible information. I am taking a REAL hard look at wvo now that diesel is $3.40 a gallon. I have read lots of previous posts regarding wvo but didnt find exatly the answers I was looking for.

I have a 35 gallon transfer tank in the bed already and plan to use it as the wvo tank. I undersatnd that wvo should be heated prior to injection for best results so I plan to use the auto tranny heat exchanger as the heating source. I know I need a pump to get the wvo to the engine and filters as well but pretty much hit a road block there.

1. what type of pump will pump the wvo and will the wvo gel at low temps?
how wiull itget pumped then?

2. what type of filter should I run to keep the ip as cleanas possible?

3. where should the switching valve be located in the fuel system to keep wvo from being pumped back ward into the diesel tank?

as far as storage of the wvo, no problem. I am concerned with reports that the wvo must be water free. How can you be sure that it is water free?

If anyone out there has extensive use of wvo and has done all the leg work that I spoke of, please pm me


thanks to all

Youve already got the perfect truck for a WVO conversion. The stock lift pump is great for that. Id look at any heated filter that allows 60gph or so. vormax? davco? fleetguard? Mounting it is a pain. Id go under the bed with it.
You need to cut the lines around the ip fuel inlet, bypass the fuel heater/strainer and run barbed fittings on the lift pump. lift pump should be fed the output of the fuel selector switch (which has the filters in line) from diesel and veggie tanks.
To dewater the oil you can use a vacuum/heat method in an old air tank or just heat and spray in a barrel. do a search for 'crackle test' to show water content. Theres test kits too but theyre $$$.
Some folks advocate washing the oil to get the acids out of it, but I havent done that yet.
WVO will gel at low temps. thats part of the reason for the two tanks. you always start and shutdown on diesel. select diesel and veg return to purge any veg in the fuel system. then switch to diesel / diesel and shutdown.
Coolant heat will heat the lines and the tanks around the fuel pickups, thats why you use so many heat transfer components.
Not a good idea for short trips, should be run on a hot engine to properly combust.
