DIESEL PARTS / FUEL FILTRATION AND WATER SEPARATION

# Fuel Filter Drain Valves & Sensors

Need a fuel-filter drain valve or water sensor? Match the filter housing and drain arrangement before selecting replacement parts.

Share the filter or housing number and your equipment details. We can help identify suitable filter, separator or service components.

## Choosing the right filtration system

Drain valves and sensors attach to specific water-separator or filter housings. Match threads, seals and sensor connection details.

## Identify the correct Fuel Filter Drain Valves & Sensors

Send the installed housing/element numbers, drain component images and any sensor connector details.

Include the original housing or filter part number, whether the part is primary or secondary filtration and whether a water separator, heater or drain is involved. The mating assembly determines selection.

## Element, assembly or service-kit decision

Ensure the replacement matches the actual separator arrangement and restores proper sealing.

Determine whether the part needed is a replacement filter element, a complete base or housing, a water-separator component or a maintenance kit. Follow application-specific service requirements.

## Fuel Filter Drain Valves & Sensors: numbers and identification

Related names include diesel filter water drain, water sensor, fuel filter drain valve. Match the element or housing number, sealing arrangement and equipment application.
