Right pump for my application

After several attempts to get the right pump for my application, it was suggested by service department that I purchase the 20gal/100 stroke pump. It’s working great! Thanks

The HP-100 is a great piece of hardware!

Using the HP-100 is easy. The pump is a solid, quality product. The ability to change between 1/4 and 1/2 gallon throughput per stroke is a nice feature. Respect!

Hi Shane,

Thank you for your review. Glad to know the pump is working well for you.

Thanks again!

Fantastic Product

1/2 Gallon mode is real easy to pump for me as I am getting older.
Price to performance is unbeatable. When the power is off and no 12 volts available, this will be worth it’s weight in gold!

Gregory,

We appreciate your stellar review! Thank you for your order :)

Replaced another leaky Fill-Rite

This is the second Fill-Rite replacement I have bought, and I am a big fan. I got tired of rebuilding the Fill-Rite pumps that came on my 30-gallon Handy gas caddies. Bought my first GPI replacement about 3-4 years ago and it has been a strong performer. When the second Fill-Rite pump sprung an aggressive leak the replacement with a GPI was a no-brainer. Best part is - this one is even smoother and easier to turn than the last generation. Plus, it's made in the USA! Thanks GPI!

Hi Rick,

Thanks for the awesome review! That's what we like to hear :)
