Works Great

Our old pump that came with the farm finally broke after we owned it for almost 20 years "no sure how old it was before we owned it". We replaced it with this one and it pumps much faster than the old one. Let's see if its still working 20 years from now.

Highly recommend!

Great pump. Performs as described. Has taken a beating in short period of time and still working as it did straight out of the box.

It will pump fuel when you need it to

I love the way it pumps fuel I never new it was so good to grab the nozzle and start pumping without having to work on it.

20 gallon per minute fuel pump

Good product for the price. If you're in the market for a fuel pump don't cheap out spend a little more on a good quality product made in the USA. You will not be disappointed with this product, very well-built from heavy quality materials.
