I bought a used Benjamin Discovery .22 and hand pump. I learned right away the pump is not my way to go. I went to the internet and tried to buy a tank/filler tube, and they were sold out. I went to my local scuba guy and he offered free air for life with the purchase of any tank. Good deal. I asked if he could supply the K valve and tube. Yes. What I got was a k valve and connecting tube. The tube was too large diameter to connect to the male check valve because of the add on muzzle attenuator. I took the smaller diameter tube from the pump and that solved the connection problem. Now, my question: The tank I borrowed is pumped to greater than the 2000# required in the green zone on the Discovery. I cracked the valve on the reservoir tank and the pressure gauge on the Discovery went immediately into the red. I shot it into the yellow. it took 15-20 shots. BTW at 15 yards the premier pellets create one ragged hole once I got used to the trigger and follow thru of the gun. Do I need a 2000# regulator? thanks for your assistance. The tree rats are going to be in big trouble.
regulator?

You need to take the stock off and inspect the air tube very closely for bulging be for you fill it again. You never wait to fill a pressure cylinder fast. Good thing for safety ratings. You can get a regulator but most people just slowly crack the valve and self regulate to what ever pressure they like.

Oh yeah, I remember the hand pump - I too, learned the rascal was not the way to go. So, I went online to Joe Brancato of airtanksforsale.com and he set me up. I don't have a place that can air up a tank to 4500 - my tank can take 4500, it is a- 66 cu.ft. tank. So, I bought a high pressure compressor simply called a "Shoebox" compressor from Joe. He sent everything I'd need to air up my air guns to me - Lord knows, I didn't have a clue, but Joe knew just what I'd need - and he didn't try to sell me more than I needed. What I didn't buy at that time was a regulator to go between the 4500 tank and the Mrod.
Well, about a week ago I called Joe back up and asked about a regulator (I saw him using one on YouTube and realized that that is just what I needed).
Well, I can tell you, I love the regulator I bought from Joe. The regulator has two gauges, one for the high pressure "in-coming" side and a second gauge for the lower pressure out-going air I control the amount of pressure leaving the "out-going" side.
For the longest time I just connected my Mrods straight to my 4500 psi air tank. (I was advised to NOT get a 3000 psi SCUBA tank, because it would never fill my Mrods to the 3000 psi they could take). With the Mrods connected directly to the 4500 tank, I was real careful not to open the tank value too quickly, I feared over-filling the Mrods.
Well, now that I have the regular, that is no longer a fear. The regulator inserts between the 4500 tank and the Mrod. So, now I connect the Mrod to the right side of the regulator (with the tube Joe provided) and when I turn on the 4500 tank, the tank sends high pressure air to the "air-in" side of the regulator - that gauge (the one on the left, as I look at the regulator) immediately goes up to 4500. The gauge on the right side of the regulator will read 0. Then, all I have to do the rotate the big black knob on the regulator clockwise and watch as the gauge on the right climbs up to 3000 psi.
When it reads 3000 psi, I looked at the Mrod's gauge and it read 3000 psi, also - no surprise there. Now, to disconnect the Mrod from the regulator. All I have to do is rotate the big regulator knob counter-clockwise and I will hear the air escape as the gauge returns to zero. When it is back to zero, pressure is gone from the Mrod and the Mrod can be disconnected. And, on the in-coming side of the regulator, it will still read 4500. This regulator is so cool - should have bought one years ago!
BTW, though I don't do it, you can leave the Mrod tethered to the regulator, keep the out-going air pressure at 3000 psi and shoot "forever".

Wager, is correct, if you don't use a regulator - SLOW - is the key word. Open the tank's valve slowly - the charge will be at 2000 psi in the blink of an eye if you don't.

I would recommend that you call Joe Brancato of airtanksforsale.com and let him recommend what you need in way of a regulator.
