GSS242 at 190 LPH should also be fine, just that GSS340 at 255 LPH was what I already had in the garage.

No problem using it on lightly modified NA8, but did read on Miata.net early last year when I was swapping fuel pumps that some thought they might over time. Quick look on the big forum just now found this:

Don't think it's the so called 'black wire' issue but worth checking continuity at outer top of tank in case it's variable:

I'm not making fun, but do you mean Walbro?
There are knock offs rife on the internets all of them advertise a flow rate far exceeding their capabilities. Just wondering if there is actually a Walpro branded one that you've been eyeing, and if so, stay away. Genuine Walbro's are cheap enough as it is, compared to Bosch, so make sure you do your homework and buy from a reputable shop.
