Hey all
are NA and NB fuel pumps compatible? as in are they the same fitment?
Cheers
Alex

Alex, as an example if you were to use a Walbro as a replacement, then you could use the same pump, but a different Walbro fitting kit would be required. So pumps should be interchangeable, just reuse original fittings of the MX5 it's going into. They don't show NB here fitting kit here, but I've certainly seen others offering either NA or NB fitting kits, although the difference is fairly minor I believe:
