Here is my gauge panel sitting in place prior to epoxying it down. I drilled extra holes in the panel for oil pressure warning lights. I need to figure out another place to mount a second set of warning lights that are more in my line of sight.

I'll be running two low oil pressure warning lights. The orange one will be between the pump and accusump, and the red one between the accusump and motor. Any reason that won't work as an early detection system? Also, any idea on how many seconds an accusump will maintain full oil pressure?
