Re: Paranoia about the D3-110 Volvo Penta - diesel bug

I understand. We have the same setup. The dual racor (A vs B) and A+B if one wishes.  We keep the 2 micron on both A and B and use only A or B, switching back and forth.  Filter C is of course the very pricey Volvo-specific filter/fuel water separator, which is what I want to spare by using the 2 micron.  I watch the pressure gauge on the racors a lot.  That’s why we change frequently, to keep pressures low.  We have no pre-pre filters.  

I remember a thread on this about a year ago, the 2 micron pre-filter argument.  That’s when we switched.  Its hard to be scientific when we have limited data re what works “best.”

Great comments on why to keep the tank full during storage.

1) FilterA only
2) FilterB only
3) FilterA and FilterB in parallel

Do you run the 2 micron filters here?

On my D3-110C there's a Volvo spin-on filter (2 micron) on the engine itself. We'll call that FilterC

Did you install a pre-filter before the Racors??
