Multiquip 48185 Diesel Tank 10 Gal HTX/STX Gen 3

The Multiquip 48185 is a genuine OEM Diesel Tank 10 Gal HTX/STX Gen 3 designed for HTX6H ride-on power trowels. As a direct Multiquip OEM component, this tank is built to the exact capacity and dimensional specifications of the original unit, ensuring a correct installation every time. Sourced directly through authorized supply channels, part 48185 is the right call when you need confidence in fitment and fuel system integrity on your HTX or STX Gen 3 machine.

Key Features

• OEM Fuel Containment Integrity — Manufactured to the exact 10-gallon capacity and sealing specification of the original tank, so fuel volume and containment performance match what the machine was built around.
• Direct Bolt-On Installation — Mounting points, inlet, outlet, and vent fittings match the original HTX/STX Gen 3 configuration for a straightforward swap with no bracket fabrication or line rerouting.
• HTX/STX Gen 3 Compatibility — Confirmed fit for HTX6H ride-on power trowels in the Gen 3 platform; always cross-reference your model code before ordering.
• Uninterrupted Runtime — A properly sealed, full-capacity diesel tank keeps fuel delivery consistent to the engine, supporting continuous troweling passes without fuel starvation or premature shutdowns.
• Fuel System Safety — A cracked or leaking diesel tank creates fire risk on a live jobsite. Replacing a damaged tank with a genuine OEM unit restores proper containment and keeps your crew working safely.

The diesel tank is the primary fuel reservoir for the ride-on trowel's engine, storing and supplying diesel at the volume needed to sustain extended finishing operations. A full 10-gallon capacity reduces refueling interruptions across large concrete pours, keeping the machine running through long finishing windows. When a tank cracks, warps, or develops a leak — whether from impact, age, or corrosion — fuel delivery becomes unreliable and the machine poses a safety hazard that takes it out of service until the tank is replaced.
