The Multiquip 12125644600 Sub-Tank Bracket is a genuine OEM component designed for HTX44 and STX55 series hydrostatic ride-on power trowels. This bracket mounts directly to the fuel sub-tank assembly and is built to exact OEM specifications, ensuring correct positioning and secure fitment on the engine fuel system. Confirmed compatible models include HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HTXD6i, and STX55Y6. Sourcing the correct Multiquip 12125644600 means no guesswork on fit — this is the same bracket supplied on the original machine.
Key Features
- Genuine OEM Construction — Manufactured to the same dimensional and material standards as the original bracket, ensuring proper sub-tank alignment and secure mounting on the fuel assembly.
- Direct Bolt-On Replacement — Matches the original mounting hole pattern and hardware interface, allowing straightforward installation without reworking the surrounding fuel system components.
- Broad HTX44 and STX55 Fitment — Verified for HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HTXD6i, and STX55Y6 hydrostatic ride-on trowel models.
- Fuel System Stability — A correctly fitted sub-tank bracket keeps the auxiliary fuel reservoir firmly located, preventing movement or vibration-induced stress on fuel lines during operation.
- Fuel Line Integrity — Proper bracket support reduces the risk of chafing or disconnection at fuel line junctions, helping maintain a leak-free fuel circuit on the trowel.
The sub-tank bracket is a structural mounting component that secures the auxiliary fuel sub-tank to the machine frame on hydrostatic ride-on trowels. It holds the sub-tank in the correct position relative to the engine and fuel feed lines, preventing movement caused by machine vibration during finishing passes. When this bracket is cracked, missing, or incorrectly fitted, the sub-tank can shift under load, placing stress on connected fuel lines and fittings — leading to fuel leaks or inconsistent fuel delivery to the engine.
