I have one with the solenoid valve which can be controlled automatically with a pressure switch or manual over ride.
I prefer a manual tap tho --just less things that bugger up
The tap needs to be handy to the driver and needs to be discreet, as these things aren't supposed to be in the cab.
Plumbing :--- from the engine -- through the filter --through the cooler (optional) -- from the cooler or filter a non
return valve then a T from the accusump to the engine.
The poor mans dry sump is good but it doesn't fix
oil surge !
