But I wanted to be really thorough: I used a grass jar, put 2 holes into the lid, put 2 hoses thru there and used black hot glue to seal the 2 holes with the 2 tubes in there. The tube, which goes to the bottom of the jar is the one coming from the suction tip in the diff. The other tube will remain closely under the lid - and I also placed a hanging bottle cap under this shorter tube to protect it from fluid splashes (it is hanging there on a wire).
