[QUOTE="kofkorn, post: 418955, member: 7076"] The ones I've seen have had a "T" fitting instead of the standard right angle fitting on the tell tale. I'm sure you could tee into the tell tale line but you're pressure readings are likely going to be lower, possibly even negative due to venturi action. It will depend on what the size of your tell tale hose vs the size of tell tale discharge opening. If you have a tell tale fitting with a small hole, you should be able to get reasonably accurate readings. If your tell tale is simply the telltale hose routed through the housing, then your pressure readings would be very low. [/QUOTE]
