Davco water separator filter, which one for the D12

Its a good setup of course and i do agree u can never have to much filteation but if u routinely change youre filters at every oil change then the 25 and 7 micron are more than enough if routinely serviced or changed but if u go longer with the fuel filters and dont change them at evey pm then that set up is very beneficiary

 

I thought the Davco was a water separator system in itself, the ones on my trucks are drained every month.

Just thinking about it, I would use what ever is available, even if Volvo said use one type, it really comes down to costs and availability.

 

You cannot over filter the fuel for a Volvo.
Volvo's are known for being fuelsensitive.
Englishman,i would use the 50-25-7 setup.
