Bruce and Bruce,

Nice job, both of you!

Have either of you had problems with injector fouling from dirt while testing? The reason I ask is the commercially available testers have filters built in and I'm wondering if they are really necessary. I assume you must thoroughly flush out your homemade tester initially.
