They aren't all that expensive, I just bought a manometer, to use for cking filter restriction, $27.00, free shipping, and I've seen the carb type for about the same money, somewhere, but they are out there. You can still buy the carb balance outfit, that allows you to hook up to the spigot on the carb boot, and do all 4 with one run, or you could use the type I bought, and do them one at a time. Bob!
