## Customer Reviews

### ⭐⭐⭐⭐⭐ They work good on Kohler 18hp
*by M***K on October 1, 2024*

Except for configuring the ports as needed these pumps are a good replacement for OEM. Comes with several different nipples to make it work for different applications they fit easily. Worked great on my 30yr old Kohler Magnum 18hp. This was the second one that I replaced as water got in it and froze causing the valves to separate internally in the pump. I think that I could have fixed it but these are cheap so I just replaced it.

### ⭐⭐⭐⭐⭐ Works good
*by D***T on April 10, 2025*

Keeps a old Wisconsin motor going

### ⭐ Poor quality. Odd design.  Failed at 3 hours.
*by D***N on January 8, 2024*

This was IMO a poorly designed part that had some odd weak but serviceable multi-piece connections for the fuel fittings. Maybe it was intended to be a universal part for other machines? It fit and worked fine... for about <3 hours then the internal pumping lever broke off and it failed to operate on my Cub Cadet riding mower. I'd suggest not buying this model, although I cannot find a different style on Amazon. Perhaps a different one would not fail quite as fast? Perhaps I got the only bad apple in the batch? The odd inlet and outlet adaptors, though a poor design in my eyes, did seem to work even if they didn't seem tight.
