Question

How much does it cost to modify diesel car to use pure biodiesel (B99/100)?

Answer 1

For pure biodiesel, nothing, provided you are not running the vehicle in cold weather (freezing).  

"Biodiesel is the name of a clean burning alternative fuel, produced from domestic, renewable resources. Biodiesel contains no petroleum, but it can be blended at any level with petroleum diesel to create a biodiesel blend. It can be used in compression-ignition  (diesel) engines with little or no modifications."

From a biodiesel site:

http://www.biodiesel.org/resources/biodi...  then just click on  fuel fact sheets to go to:

http://www.biodiesel.org/resources/fuelf...

There you will see cold weather information.

Answer 2

you may want to check the owners manual before you put biodiesel in your engine newer model trucks have a microchip in them that will lock the engine down if it detects unknown substances in the gas tank
