My 1973 7KCAB needs a fuel gauge repair.

I’ll assume that your fuel gauge (s) are the same as my 73 gcbc . It is a fairly easy fix/replacement . Drain your tanks .
Remove the wing root fairing/trim . With a pair of Channellock’s ( waterpump plyers ) or a small pipe wrench remove the sight gauge ring fitting - the outermost fitting , and then remove the remaining sight glass and gaskets which allow you to pull the gauge out of the tank .
The most likely cause of failure , in my experience , is a gas saturated cork float .
Call Ron Piercy at Rainbow Flying Service in Moses Lake , Washington -(509)765-1606 and ask him if he has a replacement -he had one for me . If no luck with Ron , contact me for where to get a replacement/repair kit . I’ve got the info wrote down but dont have access to it right now .
I cant type . Going back to correct all the mistakes just pisses me off . It has taken me 15 min to write this .
call me if you want and I can walk you thru it . Four oh 6 -three three 1 -oh oh 58

Hi, Hopefully you can reply to this old thread. I'm curious how many gaskets are in each gauge. Two? The factory has them listed as $11.22 each if it's the right one.

I installed an FDS FC-10 with an FT90 to keep track of fuel. I did forget a gas cap once and lost one tank of fuel in 30 minutes, noticed that looking at the wing gauge. So I’d still want the wing sight gauge to be working.
