so about 3 days ago I ran into the problem of having a dirty fuel filter (I am refering to the stock fuel filter on the 3B) and I didn't have access to a new one. The VO run from the tank to a flat plate heat exchanger, HIH, and then to a 3 port valve directly before the primer pump. Obviously my VO is not spick and span clean as I am talking about dirty fuel filters but one of those fancy racor heated filters is just not in the budget right now. So my question is wether or not anyone out there knows how one can clean the stock filter so I can run my truck on VO again, and not sputter and suck in air as oppose to fuel. Does anyone know of an economic reusable filter one can pick up strictly for vegetable oil? thanks!
