Hammond, LA Camping World had a couple of Shurflo 5.7 Smart Sensor water pumps on Clearance for $88.83.
Looks like Camping World is not stocking 5.7 pump model anymore.
Camping World is selling Shurflo 4048 and 4008 water pumps, both of which we and several Forum members have used with good success.
My third shurflo 5.7 recently quit. I called shurflo and they sent a 4048 as a replacement. They do not make the 5.7 anymore. All they wanted was the the sticker off the old pump. Warranty was still honored although pump was several months out of warranty.
