View guideUS NA/NB Miata Fuel-Tank Shells: Generation, Filler/EVAP Interfaces and Contents
US/LHD 1990-1997 NA and 1999-2005 NB Mazda MX-5 Miata factory fuel-tank shells only. Resolve recipient VIN, production/build, 1990-1993 transmission, exact installed/service identity, underhood emissions label and EVAP architecture, pump/sender opening, filler/vent interfaces, shields/pads/insulators and seller contents. Every 1999 car requires current Mazda VIN-catalog and installed-number confirmation because checked seller evidence adds a 7/1/1999 boundary not exposed by the model-year collision guide. Treat 2005 and Mazdaspeed ND30-42-110A evidence as verify-by-VIN sourcing evidence, not a formal cross-year arrow. Exclude the 1998 US gap, 2006-up NC/ND, non-US/RHD assumptions, racing cells, modified tanks, unsupported NA/NB interchange and unsafe repair or shipping claims.
