I recently replaced the water pump on my 330 SunDancer. I heard about a new pump from ShurFlo and took a chance and installed it. Turns out that it really is about the same as the one I removed. The pump for sale is a ShurFlo and it works perfect. I installed it 2 yrs ago in my '08 330. I guarantee that it works perfect. If anyone needs a good pump I will sell it for $85 including shipping. If you would like pics or more details, just PM me.
