Did anyone ever use one of these ? Did it silence the pump and keep fuel cooler than without it ?
I use one of that.
I have a big Aeromotive A1000 pump under the tank which was pumping a lot to much gasoline under light driving, so I istalled the speed regulator.
The one I have is only reducing the pump speed when the engine is under 3500 RPM.
The main purpose is to avoid to much bypass flow at cruise..... and longer pump life.
