Genuine OEM Mazda Fuel Tank Pump Union Nut BN8F-42-167 – Mazda 2, 3, 6, RX-8

This is the real thing—genuine OEM Mazda, not some aftermarket knockoff.

Part number BN8F-42-167, also known as the mount plate union nut for the fuel pump.

Fits a bunch of Mazda models: 2, 3, 6, and RX-8.

Made in Japan, exact OE spec, and supersedes GP9A-42-167.

It’s new, in factory packaging, and ready to bolt on.

No restocking fee if returned in same condition, but honestly, you probably won’t need to.

If you're replacing a fuel pump or resealing the tank, don’t reuse the old nut—just grab this and do it right.
