If you are going to run bio-D all you have to do is carry an extra fuel filter for when you fuel filter clogs (Bio-d is a good solvent and will break up any crap that has built up in your tank and fuel system of the years running filthy #2) Depending on how many miles you have on your truck it might take awhile and you shouldn't have to do it more than once or twice.
As for WVO you will need a couple extra things esp since we are all running DI engines. The basics are a separate tank and fuel system, extra filter on the truck, and a way to heat the WVO....either electric, or by coolant, or by both.
If you have any questions just post them or try

I used this site to help me get all the information I needed before making my conversion a little over a year ago.
I would reccomend building your own system (That is half the fun) but if you have a few extra dollars sitting around there are plenty of companies that make some very nice equipment/kits that you can basically slice and bolt on.
