Fuel Water Separator Marine Complete Combo - Replaces S3240

The R12H (R12T Upgrade) Fuel Water Separator is a Marine/Automotive Replacement Complete Combo that offers several advantages over the R12T model. Primarily, the cost-saving benefits make this an attractive upgrade option for buyers.

When purchasing the R12H, you'll receive 1 complete fuel-water separator assembly, 2 connection accessories, 2 plugs, 2 free filter elements, and 2 free O-rings - essentially the equivalent of buying 1 R12T assembly and 2 R12T filter elements, but at a lower overall cost. Additionally, the replacement of the R12H filter only requires changing the filter element, drastically reducing the long-term maintenance costs compared to the R12T.

In terms of material upgrades, the R12H utilizes an aluminum alloy and plastic-sprayed construction, making it highly resistant to corrosion - a crucial feature for marine applications where products can be easily damaged by seawater and sea breeze. This enhanced durability helps prevent leaks, a common issue with general filters.

The R12H filter element is designed for high efficiency, removing particles as small as 10 microns with over 90% efficiency. This level of filtration is recommended to protect sensitive fuel injection systems in inboard, stern drive, and outboard engines, ensuring the fuel is free of water and other contaminants.

Listening to customer feedback, the manufacturer has made several improvements to the R12H design. The interior of the tank now has a mirror-like surface to prevent the coating from falling off, and the upper and lower end covers of the filter element have been changed to plastic to avoid corrosion.

The installation process is straightforward. Before installation, remove the nylon collecting bowl and filter base, then lubricate the O-ring. The filter has two inputs and two outputs, with two plugs provided for the extra ports. These plugs should be wrapped in Teflon tape before reinstallation.

The R12H replaces the following part numbers: S3240, R12T 120AT, 18-7987, and RK10222. It has a maximum flow rate of 15 GPH (57 LPH) and a 10-micron filtration rating, with ZG1/4-19 input/output port threads and a 3/8-inch NPT connection size.

Regular maintenance is recommended, including checking and replacing the oil cup and filter element as needed. With its cost savings, material upgrades, and high-performance filtration, the R12H Fuel Water Separator is a reliable and efficient choice for marine and automotive applications.
