If you have an engine problem and the dealer says it's the fault of the Navman stuff you won't have a leg to stand on - ask them as well!
Seriously - how can a tiny plastic impeller hurt your engine...
I had this thing in my hand before I fitted it and you could blow through it with out any resistance at all.
The extra resistance to the flow of fuel would be similar to the addition of a couple of meters of extra fuel pipe - or a pipe joiner. It would certainly be a lot less than the fuel filter or a single elbow joiner.
