Pull ring next to fuel selector

[wburger1]

I looked at a 67 M20C and it has a ring next to the fuel selector and my 63 M20C does not.  What is it for.  Also you need small hand to turn the selector in this Mooney fuel selector..  Is that normal?

Pull ring is the tab for the fuel sump drain. Set left and pull and set right and pull.

Some people just pull it once.

"Pulling once is necessary, pulling twice is for pleasure"..opps, that what the military says. My bad.

That fuel selector also needs the required labels to pass  an annual :-)

When I was six and a half gallons of AVgas heavier, I had a piece of PVC with a notch on one end to turn it with. Now I just reach down and flick it with a finger.

Prior to ‘65, The Glass fuel bowl/strainer is up by the engine.  It is one of the many updates that came with the ‘65 model...

7.5 gallon makes it even tougher

The pull ring actually started in 1964, but the Mooney factory didn't always adhere strictly to years as they added and modified their finished airplanes.

I kindof wish you could sump the nose the same way. I can't tell you how many times I've been all strapped in and realized I needed to check the ring on the checklist so I have to pull it then hang out the door and look for the fuel spot and make sure it's not still dripping. A mirror on a stick or a bore scope would be very useful for this and checking the baggage door items.

Mine has been modified to have a typical sump drain outside.  Makes it nice when doing your pre-flight.  Also when you forget to drain it before you are walking around my arm was never long enough to reach it trough the little window.   

One time while working on my E model can remember exactly why but need to pull the ring multiple times so I made  a hook with a ling enough wire to reach the ring from the window.

Meaning you have a different selector / collator? Is this an stc for a selector from a different plane?

I wish I could just bend over and reach it.

My point exactly. Each 6.01# you lose is another gallon of Avgas and puts you closer to reaching the selector without a stick.

I can reach it, its just that yoke gets pushed to far forward and I exceed Vne

lol I'm the opposite - I have to pull on it so I can bend over to reach it

Oh, it ain’t the belly. It’s too many years of football.

Have yetti type arms.... no problem.

Oh and technically do you have a STC for that key ring split ring....   :-)

You have to bend the original ring to redo the carpet, but not a good way to bend back.  The key split ring looks like a good idea

My F POH preflight says to pull the sump drain selecting both the left and right tanks for 5 secs each.  Then sump the 2 wing tanks.  I’ve always worried that a slug of water in a tank would be drawn part way into the lines by sumping the selector first, so I wouldn’t see it there and then it also wouldn’t be visible when I sumped the tanks.  So I sump the tanks first and then the selector.

Mind you, I’ve never found even a drop of water... yet.

Cyril,

I think the procedure takes into account, the worst case...

1) If leaky fuel caps allowed a gallon of water in each tank...

2) Sumping each tank would drain the water to below the fuel line pick-up...

3) draining the fuel separator twice for the proper time, changing the valve in between.... empties both lines

This relies on the laws of physics to operate.

The potential challenges you can run into Are...

• restriction of flow in the line that would take longer than usual to empty...
• human error like not draining all the water, or forgetting to flip the valve, or not draining for enough time...

I had the mild steal fuel necks in my 65C.  I learned a lot about metallurgy, metal forming, water intrusion, and icing in one year...

Fun Stuff... remember by a PP, not a mechanic...
