Any recommendations on a hand vacuum/pressure pump kit to purchase to test my wastegate? All the local tool shops (Schucks, Napa, Sears) do not carry a hand tool which can create pressure -- only vacuum. Sure, I can find various tools online which appear to do the job, but does anyone have a recommendation on what to get?
No air compressor. I don't want to just blast air and watch the wastegate open. I want to be able to slowly increase the pressure and watch with a gauge how it operates -- which would also throw out the bike pump idea.
