Tell me whats wrong with this pic and how to fix it

Yeah, the booster fluid will drain out that way. That is what the tape is for, to keep in the booster fluid.

I had my booster fluid leak out so much it got below the line. I had to go to town to get some and found out that they have just about quit making it. I went to three different stores to find it but Advance Auto had it. Thank goodness!!
