I figured that as hard as it was to get through all of the wiring to get to the pump I was only going to do it once so I just ordered a new one. It was only $58.00 and a direct replacement. Yours may be different, but here was the one I got. SHURFLO 4008-101-A65 New 3.0 GPM RV Water Pump Revolution, 12V. I ordered it from Amazon.
