Any know where I can find the water hose from the gauge to the motor push connector? On the hose I can see Sun-Rise Polyurethane tubing OD 4mm and 120psi stamped on it. Cannot make out any other lettering. I looked up Sun rise and it seems they don't exist anymore. BassCat emailed me back, they don't carry this accessory anymore. Grainger has a OD 4mm/ID 2.5 200psi hose. I believe this will work, but I thought I would reach out and see if anyone else has had this issue.
