Multiquip 2175143S Fuel Filter with Water Drain

The Multiquip 2175143S Fuel Filter with Water Drain is a genuine OEM replacement designed for the LT12 and SLT12D series towable light towers.

Compatible models include LT12, LT12P, LT12D50B, LT12D50SA, LT12D, LT12DAB, and SLT12D light towers. Sourced directly from Multiquip, the part ensures you are installing the correct part every time.

Key Features

• OEM Filtration Integrity — Engineered to the exact micron rating and flow specification required for the LT12 series diesel fuel system, ensuring consistent fuel delivery to the engine.
• Integrated Water Drain — Built-in water drain bowl allows accumulated water to be purged from the fuel supply without removing the filter, simplifying field maintenance.
• Direct-Fit Replacement — Matches the original mounting threads and inlet/outlet sizing for a straightforward swap with no adapter or rework needed.
• Broad LT12 Series Coverage — Fits LT12, LT12P, LT12D50B, LT12D50SA, LT12D, LT12DAB, and SLT12D light tower models under a single part number.
• Engine Protection — A clean, water-free fuel supply protects injector components and prevents hard starts, rough running, and premature engine wear during extended tower operation.

A fuel filter with water drain sits in the fuel supply line between the tank and the engine, catching particulate contamination and separating water from diesel before it reaches sensitive fuel system components. Water in diesel fuel is a common cause of injector corrosion, poor combustion, and difficult starts — particularly in equipment that sits between job deployments or operates in humid conditions. When this filter becomes clogged or the drain fails to seat properly, fuel starvation can cause the engine to run lean, lose power, or shut down entirely. Regular inspection and timely replacement of the part keeps the fuel supply clean and the light tower running through the full shift.
