Review: Great pump - For a small pump it works very well. I pumped tire ballast out of 2 tractor tires , and refilled 1 tire , it did it with ease. I was very happy ,for an inexpensive pump it worked great.
Review: Ran once and never successfully primed. - I purchased this a while back to transfer waste oil. I finally got a chance to install it a few days ago. I ran it for about 2 minutes to see if it could self prime at about 20 to 40 PSI. I turned it off to see if I had a blockage in the pickup and it never ran again. I probably would not recommend this pump as a cost saving alternative to others.
