Will not prime. I have less than six feet of hose and double checked for leaks. Keeps pushing back through the suction. Mounted vertical, balls and seats are clean.

One that was in service died 7/30/24 so opened spare did not work out of the box was going to return but only has 20 days.Use of pumps is for used engine oil. I have had some that last 3 to 4 months, some that last a month and DOA.
