Several people kindly gave you the answer on what tank fill fittings you need! Next, internet search is your friend to educate yourself more. That's why I suggest that until you do, get and use a hand pump like a lot of us did while we learned by reading and learning here and other airgun' sites where your questions have been answered many times....
[Sorry guys, I worked to learn my knowledge by using my brain. Read up on it first THEN ask questions about what I still did not understand. Then later, the first 30 or fourty times I wanted to help and answered/helped people with all the answeres, but really, making it too easy ment they did not learn anything. You gave this guy several different options on getting his tank filled but he's not paying attention to what you wrote. Reading comprehension is vital]
