I use this on my old Lincoln TC for the air spring and it sure is a wonder. As many times as I start and stop, boot up the system, and then start on the go, it does the job almost perfectly. I ended up installing the pump in the trunk of my car, it's a bit bigger than the original pump. This is the second pump I have had in this car, the first was a different brand and it was loud as hell and you could hear and feel the pump even driving the car. I ended up wrapping him up to shut him up. But with this pump the box is no longer needed, I just installed the pump in the trunk next to a small can that I have to refill otherwise. I've limited the pump to 105psi with a limit switch and so far it's working great! Love it!
