The Honda 90451-ZG3-000 Nozzle Gasket A (0.8) is a genuine OEM replacement designed for GD320 and GD410 horizontal shaft diesel engines. As a direct Honda OEM component, this gasket is produced to the same specifications as the part originally installed at the factory, ensuring a proper seal without modification. The (0.8) designation identifies this specific thickness variant — confirm this matches your engine's requirement before ordering, as other thickness variants may be listed separately. Buyers with multiple GD-series diesel units should verify the correct variant against their engine's parts diagram.
Key Features
- Diesel-Rated Sealing — engineered specifically for the fuel system demands of Honda's GD-series diesel engines, where a precise nozzle seal is critical to maintaining correct injection performance
- Variant-Specific Fit — the (0.8) thickness designation is a key selection criterion; match this to your engine's parts diagram to confirm you have the right gasket before installation
- Genuine Honda OEM — sourced directly from Honda, carrying part number 90451-ZG3-000, so you receive the exact component Honda specifies for GD320 and GD410 engines
- Serial Number Awareness — Honda updates parts at production breaks, so cross-check your engine's serial number against the fitment table to confirm part number 90451-ZG3-000 is correct for your unit
The nozzle gasket seals the fuel injection nozzle assembly within the diesel engine's cylinder head or nozzle holder, preventing fuel and combustion gases from escaping past the nozzle seat. A properly sealing nozzle gasket is essential for maintaining correct injection pressure and combustion efficiency in a diesel engine. When this gasket deteriorates or fails, it can allow fuel leakage, loss of injection pressure, or combustion blow-by — all of which degrade power output and can cause hard starting or rough running in GD320 and GD410 diesel engines.
