I am currently adjusting the OH TBF to bring it up to TBM-1C specs in airfile.Major change in the 1C was fuel capacity of 726 gallons. I see the main center tank.Now the wing tanks, are these actual wing tanks and just have not had a selector on panel to select them or is this for drop tanks when so equipped? Just trying to figure out if need to put fuel in all tanks that adds up and find a new fuel selector or just all the 726 gallons to the main tank. Thanks.

Center Tank in Fuselang
Right and left main tanks in wings
Aux tanks are drop tanks.
Interesting.So in the OH TBF it does not show any aux tanks, so the drop tanks are just for show? Has main tank and two wing tanks

My mistake I have drop tank entries in my aired
I see, so would you say in the OH TBF the wing tanks in aired are wing tanks or drop tanks?

Dasuto,
I was curious myself, so did some googling on the TBF fuel tank setup. Articles advise that the original design had an
internal 335 gal tank. The 1-C was further upgraded to carry one 275 gal "ferry" tank in the bomb bay [in lieu of ordinance]
as well as two 58 gal drop tanks, mounted on the static part of each wing, just behind the main gear shaft opening. I would
assume that the ferry tank was only used for long range transport, and not used in combat situations. As such, may I
recommend that you setup your 1-C combat airfile with the main 335 gal tank and the two 58 gal drop tanks. To allow for the
versatility of the aircraft, you could then set up your DP for a combination of "normal" and "long range" missions, although
being a DP flunkie myself, I'm not exactly sure how to do it.

TBM-1C Fuel Capacity
Source: American Combat Planes c1968
2x Internal Wing Tanks = 94 US Gal. each
1x Fuselage Tank = 147 US Gal.
Total Internal Fuel (wings & fuselage tanks) = 335 US Gal
2x 58 Gallon Drop Tanks (under wings) = 116 US Gal.
Max Combat Fuel = 451 US Gal.
Max Ferry Range Add 1x 275 Gallon Bay Tank = 726 US Gal. Total
I'm thinking the Corsair fuel selector may work better although it only shows one drop tank, but the way CFS2 works if only one drop tank is used in the DP it will still use all the fuel of two drop tanks if two drop tanks are specified in the Air file. So fuel of all drop tanks in the Air file will still be available and used even if one DT is listed in the fuel selector.
Sample Air is attached below. The center2 tank entry in the Air file is at zero gallons, just change it to 275 gallons with AirEd utility for ferry flights if desired.

Thanks. Would you explain to fix this issue with the Wolfi Helldiver. When move fuel selector to wing tanks and thne back to internal, internal will empty and wing tanks seem unlimited. I think its in .cfg but no clue what to fix.

A cutaway drawing of the Helldiver from Skycorner website shows five fuel tanks. Left main and auxiliary, Right main and auxiliary, and a fuselage tank. Mains at 105 US gallons each, auxiliary at 45 US gallons each, and a fuselage tank at 110 US gallons. The Wolfi Helldiver Air file appears to have no center tank (for fuselage) therefore shows no fuel when selected. My suggestion is, depending on the fuel selector used would be to have no wing auxiliary tanks, just left tank and right tank with 150 gallons each and a center tank with 110 gallons and two drop tanks with 58 gallons each in the Air file.

My two cents...
Hi dasuto247,
let me help you clarify how CFS2 allows carrying of droptanks among any aircraft payloads.
Droptanks are treated as payloads, I am sure you know about it very well, already. How do I add or change external droptanks?
As our friends suggested above, one needs to have droptanks listed in both dp and airfile. The airfile handles the total fuel capacity, even if the droptank own dp indicates lesser amounts. So, you have to edit the total capacity for each droptank (Left and Right) in the airfile. Normally, if you need to have a working ventral droptank, CFS2 assigns the Left droptank for all aircraft carrying a single, ventral droptank, like the stock Zero or the stock Hellcat. In the airfile they are all listed with their precise names, you can't confuse them with internal fuselage tanks.
Once you entered the desired total amount of fuel in the airfile, you need to add the droptanks in the aircraft dp file, if they are not listed already. They were enabled by your airfile entries and you can test them as follows. Stand on the runway, with your engine idling and switch from the main onboard tanks to each, or single, droptank. If the engine dies, something went wrong in the airfile entries and you should go back checking them.
Keep in mind the additional weight will influence, one way or another, your aircraft flight characteristics and handling.
One word about fuel tank switches.
There are very few fuel switches, accommodating all of the fuel tank arrays one can find in all aircraft models available. The stock ones are rather limiting.
This is why Mopar Mike created the MAPE fuel switch library, that I use regularly with no problems.
http://www.sim-outhouse.com/sohforums/local_links.php?action=jump&catid=46&id=6517
With MAPE fuel switch library, you will be able to manage individually a lot of fuel tank combinations and I modified all of my 2d panels to include a popup window with them. You can check how it works in some of my latest uploads of Italian WWII aircraft conversions.
If I may add a personal advice, since you are increasing wingtank capacities you should also hang a credible, larger droptank under the wings of your aircraft. I saw in the past mods meant to carry large amounts of fuel, over 150 gallons per droptank, for long escort missions, using P-40 52 gal. ventral tanks under the wings. Not too credible.
There are a number or larger tanks available for download, like the ones created for Malinowsky's P-47D series, or those for VB and/or Alphasim P-51D, or the ones made by Dbolt for his stock F4U1 overhaul. The latter, if you are modifying a naval aircraft like the TBM, wear also historical colours.
Please, I beg you: don't use Axis droptanks for Allied planes or viceversa! Even if they look fitting for their fuel capacity, it's a mistake I made too, several years ago. I assure you the result does not look good at all.
Cheers!
