I have a Vormax currently filtering my diesel fuel- I bought it a while back when I tried to piece together a home made conversion because of lack of funds. I also tied the two "test" ports on my heads together (cackle cure) with a tee in the middle so I could plumb my wvo in through that with a minumal purge time. Could I purchase a FASS 8A pump, run a return loop, and for heat use my Vormax (take off the diesel line) and put a vegitherm before the tee? And if this works, would the vegitherm be better in the fuel loop, or between the loop and the pump?
