I went to Northern Tool and bought a water block filter
from goldenrod along with some fittings and a fuel nozzle.
I used these items and the electric transfer pump I had already to build my own version of a transfer pump station
with a filter that can block water if there is any.
I started off running 50/50 heating oil and ULSD intially. I am now running 100% filtered heating oil with no problems at all. When I need more fuel I drive the tractor to my garage turn on the pump and fill the tractor. I think my pump is faster then the pump at the local convenience store. I have had no issues at all. I am slightly over due for a fuel filter change on the tractor. I am planning on changing the filter and inspecting it for any debris that could have come from the barrels of heating oil.
I burn this same heating oil in my Reddy Heater in my garage.
