Need to find fresh water pump and replace it ,I can hear it run but do not know were it is or how to get to it. It is on a( 2003 mandalay MH by four winds)

I don't have knowledge of a Mandalay, but I would think it is in the same compartment where your fresh water fill connections and selector valve are located. Just open your outside storage compartments, and listen for it.

But the fact that it is constantly running is not an indication that it is bad. It will keep running for a number of reasons, such as a clogged filter screen (at the pump), blocked pickup tube, a leak preventing the system from pressurizing, and probably more often than anything, the "City/Tank Fill" selector is in the wrong position. Check those things out before you replace the pump.

Only leaks water when hooked up to fresh water hose. If I use the pump no leak and pump only cycles when water is turned on in coach. Thinking that the fresh water pump check value is not working. And maybe the fresh water tank is over flowing.

In what area of the coach do you hear it running? If you don't see it in any outside storage compartments then take a look under and or behind some of the cabinets from the inside. You may have to remove a bottom drawer to access it or even under the bed thru an access panel.

Found the pump under counter top in kitchen had to remove draws unbolt top and remove it. Then reach in to get at it big job, leak was at fitting on water pump. Pump was 10 years old so just reopaced it so I would not have to do it later. Thanks to everyone for the info and your time,
