[Vwdiesel] Waste Vegetable Oil

[Evans Antoniou]

i purchased mine from fattywagons.com

the way it works is: there is a resistance wire that
heats to 300F at 12v/8amps. that wire is in a
fiberglass shield that can tolerate 1000F of heat so
its safe. u use rtv silicone and cover/smear the
shield created a barrier/wall. then smear rtv on the
injector lines. place the wire on the diesel injection
line going to the injector and use silicone fusion
tape to fasten the ILH to the injction line. u r
actually heating the outside of the injection line and
that passes the heat to the veggie in the line. even
if u didnt have the wire all the silicone used is
still a good insulation especially for the winter.

i have not had any over heating issue with this system
so far.  i use the vegtherm only for the first couple
of minutes of my switch over. the fphe generates tons
of heat and little heat is lost when the fphe is
placed as close to the ip as possible.
