The guage is showing the contents of the bottom tank which is continually being topped up by the top tank. So until the the top tank is emptied the bottom tank is full.


Cheers!

From the Spitfire V Pilot's Notes: Fuel gauge and button = 20

For fuel consumption do not worry the Spitfire can fly a long time if you manage your rpm's and lean mixture, I think two hours is possible. I never tried! There are 85 gallons of fuel in a full Spitfire MKI or II. But when you reach 5 gallons look for a place to land. One last remark most of the time in the Battle over Britain like the tittle says it you are fighting over Britain your country so no problem...

I did have a look in one of my books and at 14.000 feet with 1700 rpm and 150 mph a Spitfire MKI does have a consumption of 25 gallons per hours so could keep in the air for at least 3 hours.

WRT Fuel quantity indications in the Spit only the bottom tank is a gauged. IRL the Fuel gauge reads 0 and only indicates bottom tank quantity WHEN the push button is pressed and held. As soon as the button is released the needle returns to zero.... source Pilots Operating notes

There is a Youtube clip that has been posted on this forum showing Spitfire I daily flight inspection that illustrates this clearly.

Its incorrectly modelled in CLOD

After one of the longest sorties I've flown so far in the game, which took place last night, I can confirm that the Spit's fuel gauge does work.

It follows what a poster above said, re the top tank feeding the bottom tank. I didn't make a note of the duration of the sortie, but by the time I landed back at Manston, I was down to 25 gallons, having taken off with 100% fuel.

I also had a backside like a piece of lead, and was desperate for a cup of tea. Now that's realism!

Top tank 48 gal lower tank 37 gal, totally 85 gal, fuel consumption full power approx 80 gph, cruise regime approx 35 gph. Unlike Hurricane, there is no switch modelled in order to switch the dial to upper tank, hope it will come one day.

Also note that hurrricane has a dial switch and a reserve tank, both left & right are sumped together as main tank in the Hurri, no such design in a Spit.

Fuel consumption Spitfire II PNs although they only specify maximum rpm and boost.


Later Spitfire PNs were much better at giving fuel consumption for several engine settings: Mk VII and VIII PNs

Hi

I gave values from measurement, they actually differ from game to manual. As far as I remember you get 85 gph rich full power and 35 gph lean at cruise 200 TAS (not IAS).
