[Vwdiesel] Waste Vegetable Oil

Tue Apr 3 11:59:22 EDT 2007

I've got some a2 and b4 (both gas to diesel vehicles) SVO conversion
pics up at:

http://www.alaskavegoil.org

These are the minimum I recommend for cold climates.  

Nice-looking brackets and pretty gauge pods are not in these shots.  

The interior hose routing is not pretty and gets in the way but is for
folks who live off the main roads, where the under-car hose can be
ripped off when driving 20 miles through unplowed snow. (ask me how I
know)

Will.
