The Multiquip EM509406 Fuel and Hydraulic Tank is a genuine OEM component designed for the ST-70 submersible pump. Sourced directly from Multiquip, this tank meets the original design specifications for your ST-70 unit, ensuring a direct, hassle-free installation. Verified fitment means you can order with confidence, knowing EM509406 is the correct part for your machine.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the tank walls, fittings, and capacity match the ST-70's fuel and hydraulic system exactly.
- Direct Drop-In Replacement — Mounting points and connection ports align with the existing ST-70 tank location, allowing straightforward removal and reinstallation without additional fabrication.
- Verified ST-70 Fitment — Confirmed compatible with the Multiquip ST-70 submersible pump series; always cross-reference part number EM509406 before ordering.
- Dual-Function Tank Design — Serves both the fuel and hydraulic circuits in a single integrated unit, keeping the machine's footprint compact and its fluid systems properly supplied.
- Preserves System Integrity — A damaged or leaking combined tank starves both the engine and hydraulic circuit simultaneously; replacing it promptly with a correct OEM unit restores full pump operation.
The combined fuel and hydraulic tank on the ST-70 submersible pump stores and supplies the fluids that power both the engine and the hydraulic system in a single integrated reservoir. Because both circuits draw from this unit, a crack, leak, or degraded tank can compromise the entire machine — causing power loss, hydraulic failure, or unsafe fluid loss in the field. Replacing a worn or damaged tank with a correct OEM part like the Multiquip EM509406 restores proper fluid capacity and keeps both systems operating as designed.
