Re: Fuel Selector Valve

The Jensen valve plug is no longer available. In the past there were a number of reports of the plug breaking loose from the valve stem, leaving the pilot with no way to turn the valve on or off. (Bad news if it breaks when the outlet is blocked partially or completely!) I have no proof, but I feel certain this is why it is no longer being sold.

My advice is that if you have one, and you want to keep it, do not fly your tanks down to empty, and if it seems "stuck" don't try to force it, and land ASAP.

Thanks for the feedback John. Since my valve has the "Both" option, I usually don't change tanks in flight and if I do I make sure I'm over landable terrain. Appreciate your knowledge on these things!
