AV/Hill MK4 Hand Pump 4500 psi
Want the best pump made today? Then there's only one choice: The Air Venturi / Hill MK4.
According to airgun writer Tom Gaylord, Hill hand pumps are the best in the business. Each pump is easy to maintain, doesn't break down, and field stripping is a breeze. Tom says his Hill Pump is the only one that consistently worked--and he's owned a lot of pumps!
Each Mk4 extracts the maximum amount of air from each stroke, and more air equals less pumps! For a winning combination of value and reliability, choose the MK4.

Things I liked: great pump .as with all pcp pumps ,they are not for the weak hearted . hill is the original ultra high pressure pump dont fall for the cheap off shore junk
Things I would have changed: I think they should all come with the dry pack filter . the one I got did not have that system on it as its an option thats an extra 50 clams.There is no way on earth that thing should cost that much . If it was 20 bucks ,that would be a fair price...
What others should know: by using the proper technique ,you should have zero problems with this pump . If you are handy with a lathe and a piece of 2 inch round delrin or aluminum ,you can make the adapter for the drypack and then go to harbor freight and get the drypack for 7bucks. thats what I did.
Things I liked: Seems to be made very well. It was very easy to assemble and there were no leaks with any of the fittings. Pressure gauge is easy to read.
Things I would have changed: Using plastic for the foot pad is not a deal breaker (reason for four star value rating) but making it somewhat "beefier" (thicker) would seem to keep pace with the rest of the quality of the pump. A movable arrow on the gauge would be useful for "targeting" you desired pressure at a glance. A simple Velcro strap included for use in keeping the hose in place when not is use would be a plus.
What others should know: It took me 286 pumps to fill my new Gauntlet from empty to 3K psi. My first 150 pumps were at 50 pump intervals with a short rest in between (for me) and to allow the pump to cool. Thereafter, I was using 25 pump intervals with a short (mmmm....actually a little longer) rest in between until I reached 3,000 psi. The pump performed flawlessly. This was my first experience with a PCP. I will likely gravitate towards the SCBA (not SCUBA) tank at some point but for now this pump serves my needs for air just fine. In the event I can be convinced that the air dryer is a necessity, I may add one later, but for now I'm not sure since it does not eliminate 100%. Feel free to comment...
Things I liked: nicely build, long hose, easier to pump than my previous brand.
Things I would have changed: none
What others should know: you need adapter if you use it for a benjamin brand

Is this compatible with the Diana Stormrider?
Yes. You will need the foster female QD Air Venturi Foster Female Quick-Disconnect... to connect the hose to the fill probe.
Will this work with Seneca Eagle claw?
Looking at the Air Venturi MK4 hand pump. I weigh 170 lbs. will my lighter weight cause me problems filling to 3000 psi? Also how many stroke from full empty?
Using a hand pump is hard work. Especially above 2500 psi. It will take 150-250 pumps for a 250 cc air cylinder. You will have to use all your weight to pump at higher pressure. You can only pump in 40-50 stroke sections. To keep the pump from overheating.
