Nice Upgrade
6 years ago
I bought this to replace the pump on the 15 gal ATV sprayer I had bought from TS. I spent more on this upgrade than I did on the entire unit. Bolt holes lined up perfect and I know have a lot more flow and pressure with a 2 year warranty. The original pump lasted 2 uses and leaked when I first used it.
Yes, I recommend this product.
