The car has had a manual gauge for years. If I unplug the sender unit, will the PSI lamp come on?
The car is temporarlly down so thats why I can't try it. Thanks.
I don’t think so. I ran mine unplugged for years. The idiot light will not work at all. I ended up hooking mine back up thinking it might catch my eye if there is ever a pressure issue. I run both sensor and gauge. You can easily add with fittings from local hardware store.
That means if you're fuel pump relay or it's wiring every fails, your fuel pump will cut off.
It's a redundant parallel circuit. once the idiot light goes out, the pressure switch will power the pump too. There's really no upside to removing it.
