P-51 Correct Fuel Feed System 4.12.2 & HSFX 7.0.3 / 4.13.4

P-51 Mustang Correct Fuel Feed System & gauges for IL-2 1946

For
4.12.2 & HSFX 7.0.3 / 4.13.4

Description:
IL-2 & IL-2 1946 P51 Mustang fuel tanks drain configuration has always been incorrect. The stock P51's in IL-2 1946 will drain the wing fuel tanks first then the center fuel tank. This is not correct for a WWII P51.
This modification changes the drainage of fuel to the historically configuration of a wartime WWII P-51 Mustang. First it drains the center tank then after it will drain the wing fuel tanks.
---------------

Required for this Modification.
!! Mod Activator (or similar) must be installed before proceeding !!

---------------
Installation :
1. Place 'P51-MUSTANG_CORRECT-FUEL' into your MODS folder
---------------

Will work with P-51 Mustang's listed below.

4.12.2 / 4.13.4

P-51 B-NA
P-51 C-NT
P-51 D-5NT
P-51 D-20NA
Mustang III

Re: P-51 Mustang Correct Fuel Tank drain & gauges for IL-2 1

Post by dr strangelove » Sun May 21, 2017 12:17 pm

Please note, of my knowledge of how the fuel system programming works within IL-2 1946, yes this corrects the configuration of how the fuel is used & displayed on the gauges (something which should have been corrected), the limitations of how IL-2 1946 programming works can only ever give one main fuel tank per aircraft which can be measured with a gauge or divided up to into multiple gauges giving a pseudo representation of multiple fuel tanks. Only drop tanks will use independent fuel separate from the main tank but these tanks have no way to be measured with gauges as yet. Hooks will define where damage and leaks to the fuel tank will occur again giving a pseudo representation of multiple tanks, e.g. If a wing is hit on an aircraft & it hits the fuel hook then it will leak and drain the fuel from the main fuel tank. If the fuselage is hit on the same aircraft & it hits the fuel hook it will leak and drain the same fuel tank as the the fuel hook on the wing. All damage & leaks will drain from only one fuel tank.

I hope this helps better understand IL-2 1946.

For its limitations for the age of IL-2 1946 original code (2001), it is very clever & works very well. Over the years great improvements have been made. The more i learn the more i realise how & why IL-2 1946 became such a successful flexible simulator engine. Of course its possible someone with good Java skills could change the code to make this aspect & many others more detailed :)

Pretty sure all the tanks feed the main tank. Use up the reserve tank first for 15mins to make room for fuel vapors, switch to auxiliary tanks.
once emptied, then switch to reserve for the rest of the flight (the main feeds the reserve).

A leaking wing tank will have no effect on the main tank, and vica versa.

I wish self sealing tanks were modeled.

Thanks for your work :)

Hi ! :)
Only the gauges display it as if there are multiple tanks when in fact there is only one tank , the gauges divide displayed fuel giving the impression of multiple tanks . There is no switching from tank to tank, only that one gauge will go to .0 then move to next gauge and display remaining amount. Of course it depends on the amount of fuel the user decides to take on how the gauges will divide & display the fuel load.

A leaking wing tank will have an effect on the main tank because there is only one fuel tank ;) unfortunately its a limitation of the game engine , there is only one main tank & then any additional drop tanks are independent.

Any drop tanks taken will drain first then it moves to the one main tank , this can be displayed by multiple different gauges

Self sealing tanks im sure are modeled because once the leak has stopped the fuel stops draining on gauges.

I would love to see real multiple tanks implemented into IL-2 46 . the ability to switch tanks & control fuel flow . it would also be great to see the Drop tanks measurable by a gauge

I hope this makes it easier to understand

Thanks doc.. but I was referring to the real P-51 ;)

As far a modeled self sealing tanks, the leak for a long time before stopping,
when the shouldn't leak at all or minimally. Unless incendiary rounds are used.

At least that's what I noticed. I could be way off the mark though :lol:

ok :) , i see ! sorry !

& now i know correct term for this mod

it should be ' P-51 Correct Fuel System ' :)

i do not know about self sealing but i do know that the self sealing tanks in IL-2 do eventually seal & the Japanese ones do not & will continue to leak
Actually if in reality they seal straight away like you say perhaps i could make a mod for this, but it would be classed as a cheat ?
i will ask someone who is a mechanic for war birds to see if they know some more

Self sealing tanks work through vulcanized rubber because the fuel action. Several layers of rubber, and one of them is vulcanized by fuel going through. After a time, the vulcanization by petrol action seals the layer and leak stops. Vulcanization wasn't instantaneous.

It depends on caliber of bullet and damage extension on rubber. A big caliber hit won't be sealed by vulcanized rubber action. Maximum (Goodyear selfsealing tanks in WWII) was 0.50 inches (12.7mm) bullet/impact.

Thank you for this information Willy. :)
so the self sealing tanks will only work from smaller caliber machine gun rounds ?
this makes sense, how could you recover from large rounds.

Soooooooo tried this mod. My tanks however always read full on my P-51B.. even when I only give 50% full tanks.
