Fuel to go
This pump works just like fueling at the station. Auto shut off makes it handy and safe. Connection to tank was quick and easy. I installed battery spring clamps for power and installed a lock to keep people honest.

GPI 15 GPM 12V Fuel Transfer Pump
Takes the guessing out
Makes life easy and takes the guessing or looking at the side of the tank wondering how much is in there. Works great for low volume per acre applications (2gpa).

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!
Great fast service.
Very Happy
The perfect Outlet Hose and not too heavy. Everything shipped fast and as advertised.
