I was tracing a minor leak. One of the push-to-connects had a minor leak on the distribution block that feeds the slide seal pressure regulators. In the process of looking around I turned the plastic lever that looked like an on/off, but as soon as I did that it started leaking air and there are positions where it leaks less, but it still leaks. Do I have to replace the block with the plastic lever or is there some other way of sealing this, such as removing it and tightening something?

TIA
