Picked up my new Racor filter this morning. I'll be using it on my Detroit 4-53T running wvo on a two tank system. Filter has a heated return fuel line
and an 200 watt heater element.
Electric heater for de-waxing on initial startup, with return fuel heat to keep it warm and flowing once it's running. They still manufacture many of the OEM fuel filter / water separators for heavy duty trucks to this day.
I really wanted the Davco, but the size stopped me from buying it. I just could not find the room to mount it. I was going for the model 382, but that's too large for a pickup frame mount and my engine bay is already too packed.
