The Multiquip 50379100 Water Separator Filter RW-1404 is a genuine OEM component designed for Multiquip RAMMAX walk-behind rollers including the RW1404, RW1404MR, RW1504HF, and P33/24 HHMR-BD series. As a direct factory replacement, part 50379100 is built to the same specifications as the original unit and installs in the same position without modification. Keeping this filter in good working order is essential for protecting the fuel system on diesel-powered roller equipment operating in demanding site conditions.
Key Features
- OEM Fuel System Protection — Engineered to the original design specification, this filter is validated for diesel fuel-water separation performance in Multiquip RAMMAX roller applications.
- Direct-Fit Replacement — Matches the original mounting configuration and connection points on the RW1404, RW1404MR, RW1504HF, and P33/24 HHMR-BD, allowing straightforward installation during routine service.
- Broad Roller Compatibility — Confirmed fitment across multiple RW1404 and RW1504 serial number ranges, including RW1404MR units from S/N 326075 and up, as well as earlier RW1504HF units up to S/N 1534188.
- Fuel Injector Defense — Removing water from the fuel supply before it reaches the injection system reduces the risk of injector damage, rough running, and hard starts that contaminated fuel causes.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, part number 50379100 carries the full backing of the OEM, giving you confidence in part quality and compatibility when it matters most.
A water separator filter sits in the fuel supply line between the tank and the engine's fuel injection system. Its job is to capture and hold water that has entered the fuel — whether through condensation, contaminated supply, or environmental exposure — before it can reach sensitive fuel system components. Water in diesel fuel causes accelerated injector wear, corrosion inside the fuel system, and loss of engine power. When this filter becomes saturated or clogged, the engine may run roughly, lose power, or fail to start, making regular inspection and timely replacement a key part of diesel roller maintenance.
