can someone tell me the size of the vac hose that connects the nipples of the two diverters?

The passanger side diverter is connected to a metal tube, and then theres a line that runs from that tube to the drivers side diverter. This is the line I am talking about. Im expecting it to be 1/4" and 5" in length,

but I dont want to take it off to measure because ill be rideless if i cant get it back on before the new hose arrives.


kind of a silly question, but it would help alot!
