By Vernon from USA on 2011-09-26 14:00:43Things I liked:I got a Hill MK3 pump because the farm is 100 miles from the nearest filling place. I completely emptied a Sam Yang dual tank Dragon Claw rifle to see how long it would take me to fill the gun by pumping and it took 700 pumps to reach 3000 psi. From 2000 to 2500 psi takes 100 pumps and you have to stop to let the pump cool down. 2500-3000 psi takes closer to 120 pumps and takes quite a bit of effort on both the up and down stroke. I had been filling the gun inside an air conditioned house without using the desiccant. When I went to the farm, the humidity increased throughout the day and I swear it got harder to pump the more humid it got. I never did see any water vapor from the gun on any of my shots so that indicates to me the desiccant was adequately removing the water vapor.
Things I would have changed:Pump does what it’s supposed to do, produce high pressure at low volume. In 80°F weather I can do 50 strokes at 2000-3000 psi before the pump gets warm. Change the hose length, 1 foot is way to short! Make the base bigger. It works but you have to be on something hard, on anything slighty soft you start burying the pump.
What others should know:If filling a gun from zero pressure, you can pump a couple hundred times before the pump gets warm. When you get the pump, take off the bottom brass guide of the outer cover and check for debris. Mine had a piece of the o-ring in the threads.

By Paul from USA on 2014-07-09 17:53:58Things I liked:When it was new it seemed to work fine. A month later with not much use it started getting harder to pump. Sent it back twice to be repaired, never worked right again.
What others should know:Have a Benjamin pump I got before the Hill and the Benjamin is still going strong after over a year of heavy use.
