This post came via Girl Mark about a pump that can be used with B100 in home heating oil systems:
Bioheat users and interested persons:
There is now an affordable B100 compatible pump available that will
allow you to use B100 in your home furnace. Most of you use the
standard B20 to B30 blend that is compatible with your furnace seals.
This new little replacement unit is only $93.36 and will allow you to
step up your blend without worrying about your furnace seal material.
Check out the link below for more information.

Hope this excites some of you heating your homes.
Biodiesel, wood, and solar are the few readily available renewable
choices for home heating. Its now simple to turn that old oil hog
furnace into a greener heating machine.
