Champ/Chief nose tank fuel valve discrepency

Post by AV8R2 » Thu Jun 10, 2010 19:16

This is urgent!

It looks like I am going to need some feedback; the more the better......

I seems that there is an error in the original data (drawing) on the thread size that is in the nose tank outlet fitting.

According to the drawing, the 1-2403 valve, in that location, is 1/2" tube with compression nut on the valve outlet and
3/8" male pipe thread with the screen soldered into the end.

According to 3 different owners now that thread is 1/4" pipe, not 3/8". Which is correct? I am beginning to suspect an error in the drawing.

Please contact me by email (please not on the forum) at burl@biginalaska.com and let me know which male pipe size you have on your aircraft going into the nose tank; 1/4" pipe or 3/8" pipe. Production is being held until I can find out for sure which is correct.

Blue skies and tailwinds to all!
