fuel pressure switch i think you mean water sensor. remove it from the old unit, replace the o-ring, and install it on the new unit. check it for leaks before you install the new filter.

You do not need it. install as is and secure the wires that arnt being used

I was talking about the fuel Persure Switch I have also seen it called a Vacuum Switch
it mounts on the front of the filter base and is the size of a dollar coin white in color with two wires coming from it. the base came from I site I got from here its call //www.oem-surplus.com the part number for the base is 12471725 I have added the picture for it as well. CUCV 1833 I do not need the switch with this part number as it is the Civy one ?

Thanks for you help
