Pupm leaks and makes a mess

I can't get the pump to hold pressure. I'm able to pull up on the nozzle which breaks the suction/pressure. I'm back to the 1gallon jug & pump from Amazon.

The pump itself is of an good/excellent quality. Where the pump takes a bit of a dive is where it connects to the 5-gallon bucket. The pump has a narrow-range to remain straight up and steady while pumping. Bending of the pump unit occurs when pumping force is applied toward the front of the pump handle causing it to bend forward due to the soft plastic bucket connection.

My horse loves the W-3 oil, she has never looked better and I am very happy with the 4L bucket and pump. It is very convenient and also cost effective. Thank you!

pump is fine, getting it into 5 gal bucket was a learning curve. I keep a yogurt container under the pump to catch the drips.
