I bought this pump to replace a five year old pump that shorted out at the switch. Pump has performed great. I was disappointed that the new pump did not come with a new power wire like my other pump had when I purchased it. When the switch shorted out on the old pump he melted the insulation off the old wire making it unable to reused.

I used to have a 15gpm pump with a 3/4” hose. The fact that this 20gpm pump lets you run a 1” is a huge upgrade. I have a 85 gallon diesel fuel cell that I can empty out twice as fast as my previous pump.
