Just bought a used Magnehelic off of ebay for 25$ plus shipping. It goes from 0-1" WC. Since I installed my P43 myself I wanted to check the draft trim adjustment. The mag came with a case and a hose but I need to find an adapter to fit the test port on the P43. Can someone tell me what size I need to find or if you McGyver'd your own how did you do it? Thanks!
