I would highly suggest ditching the titan as your air source. Sure it seems like it would be the "best" air tank to use here it is also going to create a ton more hassle for you to use it as it is much larger then the recon body.
I'm ditching the stock altogether and putting the air tank at a right angle from the plunger, next to the pump. I have a spare titan and a spare recon, I'm just throwing this together and having fun with the ergonomics.
The connection from the pump to the tubing is still leaky, gets 40-50 feet with taggers with the head torn off. No real trigger system other than directly pulling the titan tank, still need to reinforce the entire thing and I have no idea how to activate the tank from the recon trigger.
