Gary,

I recently attended a veggie oil conversion workshop here in Portland.  A
couple of thoughts regarding what we did......

1.  The sense I got from the workshop leaders and several other attendees is
that the single tank Elsbett system is prefferable over the various twin tank
systems.  Its more expensive, but simpler in the long run.

2.  We installed a more traditional two tank system during the workshop
because Elsbett didn't have injectors for this particular vehicle.  A
chevrolet 6 port valve is used to switch between tanks and a three port valve
is used to backflush the veggie oil from the lines etc. with diesel before
shutting the engine off.  The diesel fuel used in the backflush does end up
in the veggie oil tank but isn't considered to be a problem.
