I need an adaptor for adding air at a gas station

I am now living in Ft Walton Beach FL and have not sold my house and moved all my stuff yet. I usually checked the air in my garage and added air with my own air compressor. I now have free air at Eglin Air Force Base where I work but the air chuck will not get on the tire. I have the Fobo t-valve and the air chuck just will not go on and seal.

I need an extension that clips on or something

If you have battery tender out let, you can plug a slime air compressor into it. I have a Gerbing out let that I plug my slime compressor into.

I was stationed at Eglin AFB during my EOD days. I use my home compressor as well and when I'm on the go I use my Motopump (awesome). If the Eglin air is still calling you then why not try something like this https://www.amazon.com/CyclePump-Cli...lve+stem+chuck ?
