Some list member in the UK asked about LPG conversion for the vanagon
recently.
I finally got around to installing a propane fuel system on my 1987 syncro
westy.  Its a duel fuel system so the original digifant is still in place
and functional.  You just flip an electrical switch on the dash to change
over, even while driving.
Propane in Canada is a lot cheaper than gas or diesel, less tax.  In Alberta
its almost half the price of gas.
Range has almost doubled also.  To bad I don't have 11:1 CR to take
advantage of the 115 octane though.
Overall cost per mile is same or a little less than the 1.6 TD westy I had,
but there is a LOT more power.
Around here it seems there are more places to buy propane than diesel, so it
is a practical motor fuel (where I live that is). My propane/gas Jetta has
10,000 km since I converted it to propane, I've only driven less than 50 km
of that on gasoline.
