My 63 M20C needs new fuel caps (thermos type)... Anybody ever have any luck finding these new or used? Or what other options are there ( non-cert maybe ) ?

Thanks

Your experience may be different....

My experience came from my 65C.

They are available new from your MSC. Check your fuel neck to see if has been replaced with a SS part.

Often, the one you have can be fixed up to work properly.

They are more expensive than you want to pay....

What is wrong with your current ones?

The cams can be built back up with the help of a welding mechanic.

Search for a thread based on that idea. It has been done a couple of times...

Comanche caps are non vented, Aztec caps are vented and will vent fuel out the top of the wing in a Comanche.

Post a picture of what you have, marauder will turn it un-sideways for ya....

We'll all get a look that way.

My 65C had plastic fuel caps when I got it. The cams were worn off. That's where I started to learn the rest of the details above.

I bought the expensive caps and found they didn't fit in the rusty old fuel necks. That was the end of my M20C experience.... It was a one way trip to an MSC.

Unfortunately, there was no MS back then...

Best regards,

The Q and A on aircraft spruce says the caps are 2-3/8 inch diameter....my current caps are 2 inch diameter.

Are you sure these will fit?

Doesn't make much difference if they fit or not. There must be a legal basis (Ie FAA paperwork) to install them in a Mooney. And if someone has said paperwork you'll need to purchase the certification paperwork from them.

Mooney was out of stock, they gave me the part number to give to shaw...

Maybe one could try to use the top of a PA-24 cap "new cam" ($85) with the bottom of the 2 inch Mooney cap... The top and bottom unscrew ...
