" Affected vehicles may be equipped with a fuel pump module manufactured with low density impellers .
The Recalled vehicles will have the fixing checked and corrected as necessary by an official HONDA
MOTOR CO service
The affected fuel pumps will be replaced "
I interpret the words I have highlighted in red as meaning Honda source their OE petrol pumps from 2 (or more) independent component manufacturers, and cannot tell from chassis number which brand will have been fitted to a particular car. Even on the same day some cars may have got brand A until stock on hand ran out, the remainder got brand (or batch) B
I suspect Honda have only initially financed a visual inspection, from which it may be obvious which brand of pump has been fitted. Honda may only authorise the extra cost of disconnecting and replacing the pump on on those cars with the dodgy pumps.
Replaced pumps will come with a new filter. Those not replaced will still have their original, possibly dirty, filter.
If your pump is not replaced you might wish to get the filter changed anyway while the car is partially dismantled at Hondas expense . But this may involve extra dismantling, and the cost of a new filter. The question is who pays for this - and how much. You shouldnt have to pay the full normal cost of a filter replacement.
If I am right that some pumps are not replaced on this recall the dealer should ideally agree with you in advance whether in the event the pump is not replaced you are willing to pay a bit extra for the filter to be replaced.
