 |

Folks,
I have a Gretz Heated Pitot Tube and mount. Unfortunately the pitot tube
fitting does not extend far enough to be able to attach the line to the tube
once the tube is in the mount. I'd like to hear from anyone that has found
the solution to this problem so I don't have to "reinvent the wheel".

Marty, it's been a bizillion years since I installed my Gretz Pitot
tube so I can't offer much other than a few pictures. Here is the
technique I used and maybe it will help you out.

What I have done in the past is to extend the line from the wing down
through the mount so you can attach the line externally, then push the
pitot with the attached line into the mount and secure. Then later it
is servicable without opening the wing.

Hi Marty,
Here are some detailed pictures of my Gretz Heated Pitot in the RV-8. Might give you some ideas:

Marty,
I made a pair of short AN4 tubes that connect inside the mast and extend
outside (up in th the wing). There I have a set of AN4 connectors that
allow me to disconnect the 'mess from within the access panel.

Nice installation Matt, but my Pitot was purchased long ago without the
electronic module and the tube sticking up from the pitot is only about 1.5"
long, terminating in a AN4 tube fitting.

Loosen the screws holding the mast (mount) to the wing and push it up inside
the wing. This will leave the end of the tubing exposed where the flare nut
is so you can attach the pitot to it. Then pull the mast back down and
reattach it. Thats how mine works...hope this is your answer.
