Now that you're resolved your water mystery Steve and replaced the pump I hope you've kept the old one. Go on E-bay and get yourself a re-build kit for the Shurflo pump and keep it as a spare. Back in March while at a CG I noticed water dripping from my filler. There is a check valve that allowed water to by-pass and flow into the tank while hooked up to city water. I had an old pump handy to change it with and now need to replace the pump head and keep it as a backup.
