Also that fleetguard next to the CAT filter is a oil filter that's a kit for the cummins diesel engine.
FS19594 seems to be smallish compared to the stock Mann Filter. Im most concerned with the flow-rate so im assuming smaller media means more restriction. Im bit-worried also that Navara D40 Diesel has no lift-pump w/c means the fuel pump is doing all the sucking from the tank.

But on hind sight, im thinking that Nissan did installed a stronger sucking pump because they would not fit two filters in-line using 3/8 hose without considering the restriction.. Spain-built Navaras only have 1 fuel filter, and what we got from Thailand is tropicalized for bad-fuel so it gets 2 filters.

Im planning to replace primary filter with B41212, problem is the WiF sensor will be useless
The primary filter will be replaced by High efficiency (2micron best-effort, they said 4microns is what kills the CRD injectors). And to compensate for the restrictions, fuel line might be upgraded also.

Now my problem is the WiF (might consider to retain the primary for the WiF functionality).
Also i could'nt find 1-14 filter-head with primer-pump. Would'nt want to compromise without bleeder-pump because its handy during roadside troubles, and It would be ackward to always bring the pressure pump. The one sold online is Parker/ Racor marine-grade filters and it cost a fortune.. Do you have alternative part for that?

Crosses for the part without pump - Donaldson P562262, Cummins 142784S, Baldwin FB1311
Parker has 1-14 but i dont know if gasket of common filters like CAT IR0750 would fit in that

Everything back on scratch-board because of the WiF and bleeder pump..
