Pressure switch problems....Again....

Hello Wiz...
I am still having problems.... I see Larry at Delco gave a guy some advise that I may be able to use.
My system has the pump...then unloader...then pressure switch...then hot box...
I should have the switch before the unloader?? I think.
Or should I have the switch mounted on the pump itself (manifold) I had seen one mounted in one of the top spaces on the pump manifold.
Any info would be helpfull.
My hot box isn't shitting off. I've tested the switch and it works great.....

Keep your stick on the ICE

The Pressure switch should be on the pump head or on a Tee just before it goes into the unloader between the unloader and the pump. The switch should be normally open and it closes when there is pressure pressent. A great upgrade to a pressure switch would be a flow switch. They tend to last a little longer.
