Hi Josh- I was looking at new Racor filter units and this was the information Defender provides. That sounds like the reverse of your recommendation?
Turbine Series filter assemblies are designed to be installed on the vacuum side of the fuel transfer pump for best efficiency and protect precision engine components from dirt, rust, algae, asphaltines, varnishes, and especially water, which is prevalent in engine fuels. Racor’s system diagram is the same: fuel tank, Racor, Lift pump, secondary filter, engine S/V Aries 1990 C&C 34+ New London, CT > On Sep 23, 2021, at 10:37 AM, Josh Muckley via CnC-List > <cnc-list@cnc-list.com> wrote: > > I'm late to this discussion, sorry.
