The Honda 19104-ZA0-800 Reserve Tank Tube is a genuine OEM component designed for the EX5500 generator. As a direct Honda OEM part, it is manufactured to the exact specifications required for this application, ensuring a correct, trouble-free installation. If the reserve tank tube on your EX5500 has cracked, hardened, or begun to leak, this is the correct replacement to restore proper function. Confirm part number 19104-ZA0-800 against your unit's parts diagram before ordering to make sure this is the right tube for your serial range.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this tube meets the exact dimensional and material requirements of the original part it replaces on the EX5500 generator.
- Correct Routing Fit — formed to match the original routing path between the reserve tank and its connection point, so this part installs without reworking or adapting the line.
- Targeted EX5500 Fitment — designed specifically for the EX5500 generator; verify your serial number against the fitment table to confirm this is the right tube for your production range.
- Leak Prevention — a tube that has cracked or stiffened with age can allow fluid to escape the reserve circuit; replacing it with this OEM part restores a sealed connection and keeps the reserve system working as intended.
The reserve tank tube connects the reserve tank to the main fluid circuit on the EX5500 generator, allowing fluid to flow between the two as operating conditions change. This flexible line maintains the integrity of the reserve routing — keeping the system topped up and preventing air intrusion or fluid loss. When the tube cracks, hardens, or collapses with age, the reserve circuit can no longer function correctly, which may lead to fluid loss or inconsistent system operation; replacing it promptly keeps the generator running as designed.
