It's for just what it sounds like, valets. When you flip the switch, it powers the pump way down. So when you have the grungy lookin guy at Goodyear do an alignment on your truck, and you can see that glimmer in his eye when he goes to test drive it, you flip the switch so that the your truck turns back into the dog that it was when you first got your hands on it. I can just picture leaving it there with them, those guys are probably tellin all their friends, drinking beer, and doing donuts with my truck. Maybe I'm a little over paranoid?
That's genius, PT. I wasn't sure what you could limit to cut down on the power, being a mechanical pump and all. I thought maybe a limiting valve on the fuel line, but that sounds like it would just be hard on the injection pump.
Anyway, yeah, I got a couple questions. I take it that grainger part is just the valve, right. All fittings, hose, and mounting I need to buy on my own.
Second, I take it it didn't come with a switch. The valve comes with some kind of solenoid or whatever to activate it, right? You just wire in the switch of your choice and youre good to go?
