The lovecraft system is just a cheap goldenrod filter (search it) with a custom machined head that allows coolant to pass through it. The stock spin on fuel filter is gone and replaced by a fuel heater that has coolant running through it.

The bottleneck of this lovecrap thing is the "filter". That is a joke and should be illegal to be sold like that.

The hipsters and goons who put these on their car usually DO what you say and dump straight WVO into the tank without filtering. Ive read it on some of their forums. That hasnt been the case with this setup as the previous owner bought the filtered WVO from a supplier for 1.00$ a gallon. He says he always mixed it 50/50 with diesel. BUT who knows.

Does anyone know what the stock spin on fuel filter is rated at in microns? I have found a 10 micron filter that will fit this lovecraft and replace that homemade water filter with a bag ziptied around it setup.

Id also be interested in finding lower micron rated filters that would fit. If i can match the micron rating of the stock spin on filter, or come close, i may just leave the system as it is and use the better filters in the goldenrod housing.

Heres a 15 micron: http://www.northerntool.com/shop/tools/product_363415_363415

If the plastic bowl could be replaced by a big ol caterpillar or heavy truck filter id jump all over that
