That ring is not original equipment and needs to come off. The little holes on the side of the tube are the static ports, covering them adjusts nothing, it just distorts the calibrated pressure. If I am wrong - please some one correct me. Hartmut

I assume this can be adjusted, move fore and aft to calibrate the airspeed.I uploaded to picture to the photo section in 99325>Pitot.Is this correct and should we adjust on it or remove it.I will first check the static and pitot system for leaks.Mitchn99325 _________________________________________________________________ Get Free (PRODUCT) RED™ Emoticons, Winks and Display Pics. http://joinred.spaces.live.com?ocid=TXT_HMTG_prodredemoticons_052008
