Would not let me submit more than one answer to this question. Confusing.

More than 1 answer is correct

Both the 1st and 3rd options are correct. Because of the distal placement of the needle valve on a pressure compensated thorpe tube, backpressure is prevented from messing with the reading in the tube and will not affect the reading. Oh, and all thorpe tubes are made to be connected to 50psi wall outlets.
