Changing out the City Water Connector

Sch911 and Enblethen. Thank you both for your help. Since I am brand new to this I am not entirely sure what information you are asking for Enblethen. The motor home is a Class A and from my understanding it has 2 fill points. On one side is a fill connection where I can fill the fresh water tank (Gravity??). On the other side of the RV is a compartment/Hatch? where I connect the power, sewer, and city water. There is also a hot and cold drain point located in this compartment and a hand held shower. I can also turn a lever and the fresh water tank will fill thru that city water connection. This is the connection that is spraying while under pressure. The tank is a 100 gal tank. I have a picture of it but don't know how to upload however here is the part number of one that looks pretty close to what I need to replace. 62135 - FPT, Same web site you posted... http://www.jrprvinc.com/search.php Thanks again to both of you
