The four port fuel input cap offers a variety of configurations for connecting the fuel lines to the fuel water separator assembly. Simple-to-use fuel flow arrows are cast directly onto the top of the cap, indicating which direction the fuel should flow in and out of the fuel water separator assembly. This type of configuration allows users to choose from four different types of fuel line configuration. The four port fuel input cap also has a rigid mounting bracket built right into the cap with two mounting holes. This offers an easy and compact mounting solution when you are determining where to locate your fuel water separator assembly. The four port fuel cap is made from an aluminum die casting and is powder coated to offer extra protection against the elements, the perfect replacement part for your fuel filter water separator.
