Standard fuel, long body....dropped back to 89 gallons

Separate related question.  Until the long body, the M20K was 75gal and M20J 60 something, and less from there to earlier models.  My understanding is that all the metal mooneys since M20B have entirely the same wing, except perhaps details about landing gear and wing tips.  What did they do different inside the wing to make these essentially incremental changes all the way up to 100 within what seems to be the same bays, without sealing of extra bays as the monroy kit does.

This is just a wild a55 guess, but I'll bet the fuel capacities were dictated by the aircraft's total useful load.

But still - what are they doing inside the wing - are they sealing off different bays?

Gotta be.

Let's all measure fuse to cap, and count sealed panels on the bottom of the wing. Report back with capacity. Some LBs will differ only by the filler neck.

52 gallons usable in my M20C in two bays/side.

My bladder is good for a max of 35 gallons of 100LL.

Similar discussion back in 2011...

Cris and I were discussing the 89 vs 102 gallons.  The POH, and various markings...

The fun part is the writing style hasn't changed very much.  Bullet point after bullet point...

This was from my pre-retirement era by about five months...

Best regards,

Still air range in my plane with 102 gallons onboard, FL180 and 70LOP: Denver to Puerto Vallarta, with a little bit to spare. Observed this on my G1000 range display on a recent trip from Denver to Cabo. With 30 more gallons you could probably just make it to Acapulco.

The LR tanks shine west to east with a nice tailwind . A few yrs ago I planned a trip from Amarillo Tex stopping in Tunica Ms for fuel and potty and off to Wilmington  De Started in Las Vegas. With the tail winds I kept changing my fuel stop more eastward and ended up flying nonstop from Kama to Kilg that's where the long range tanks shine plus flying over crappy wx. no need to land. 1300 miles with 24 gal. In reserve left.  The Mooney advertisements still should be pushing speed and economy along with it being a personal airliner.
