I currently have 3 home brews on tap in my garage but I have everything set up for 4. A lot of people that come over like bud light. So what I want to do is use my extra co2 line for a keg of bud light. I have one of the pump style couplers already so what I want to do is take the pump off the coupler and run co2 into that space and run the beer line to my tower. So my question is will this work? I wasn't sure if there were different couplers depending on the use.
I'd just keep some cases of bl around, and use the other tap for more homebrew, or at least mineral water. I wouldn't try to mod that tap. You can buy the correct coupler in any case for not much more than 20 bux.
