I am using a Holley Blue electric fuel pump as my WVO pusher pump. but find that using cold oil the pump does not pump. Once the oil has been heated, it pumps fine.

I have a pressure/vacuum gauge at the fuel line to the IP.
The MB lift pump provides ~14psi on biodiesel/WVO blend.

I am using one of these to pump biodiesel from a 12 gallon drum, and it pumps ~20 litres/minute thru a 3/8" bore, 3' long pipe with a plastic inline fuel filter in the 1/2" suction line.
