CARMOCAR Marine Fuel Water Separator for R12T Spin-On Housing | 120AT NPT ZG1/4-19

Overview

The CARMOCAR Marine Fuel Water Separator is designed to pair with the R12T marine fuel filter and water separator assembly. Its spin-on housing supports compatible connections including 120AT NPT and ZG1/4-19, delivering a compact, tool-friendly solution for on board filtration.

Beyond the filter itself, the unit features a reusable clear nylon collection bowl that remains visible as fuel passes through the system. A self-venting drain provides controlled access to unwanted muck and water when maintenance is due, and tightening the valve keeps incidental discharge at bay while allowing deliberate drainage when needed.

This level of capacity helps provide clean, water-free fuel to your engine, contributing to smoother operation under typical marine conditions. The bottom outlet enables draining of muck and water without taking the entire assembly apart.
