Univair Fuel valve U-491-947

[mike mcs repair]

What size ball should I use to plug the valve while replacing the rings? When we did it before, the valve was off the plane during a rebuild.

sorry you gotta drain it.... ball trick only for old style valves.....

boy would you be mad at me had you tried that!!

[update] Replacing the o-ring fixed it. I had to drain the fuel, but didn't have to remove the valve.

But, what's cool about this is that I can get a nearly instantaneous answer from people who have actually done the work before. Saves lots of heartburn.

Thanks for the help.
