They are different tanks.

fuelTankSmallFlat is a volume = 100 tank

fuelTank is a volume = 400 tank

I'm sorry, my post wasn't clear. Both those tanks are duplicated.

what is happening here in propellants.cfg? 

// Fix engine propellant ratios to be whole numbers. This has no effect on
// engine performance, but it makes MFT produce nice numbers when configuring
// tanks for engines.
@PART[*]:HAS[@MODULE[ModuleEnginesFX]] {
	@MODULE[ModuleEnginesFX]:HAS[@PROPELLANT[LiquidFuel],@PROPELLANT[Oxidizer]] {
		@PROPELLANT[LiquidFuel]:HAS[#ratio[0.9]] {
			@ratio = 9
		}
		@PROPELLANT[Oxidizer]:HAS[#ratio[1.1]] {
			@ratio = 11
		}
		// just in case someone has multi-propellant engines
		@PROPELLANT,*:HAS[~name[LiquidFuel],~name[Oxidizer]] {
			@ratio *= 10
		}
	}
}
@PART[*]:HAS[@MODULE[ModuleEngines]] {
	@MODULE[ModuleEngines]:HAS[@PROPELLANT[LiquidFuel],@PROPELLANT[Oxidizer]] {
		@PROPELLANT[LiquidFuel]:HAS[#ratio[0.9]] {
			@ratio = 9
		}
		@PROPELLANT[Oxidizer]:HAS[#ratio[1.1]] {
			@ratio = 11
		}
		// just in case someone has multi-propellant engines
		@PROPELLANT,*:HAS[~name[LiquidFuel],~name[Oxidizer]] {
			@ratio *= 10
		}
	}
}

The ratio is causing the LV-T30 to burn fuel at an unequal rate leaving me with LF/O in the tank. It may not affect engine performance but it is most certainly affecting overall rocket performance. With this patch my engine cuts out at 90km traveling at 2.620km/s. When I remove MFT the rocket (flying the same kOS controlled ascent) burns to 96km traveling at 2.857km/s

Also I'm stumped why this patch is not affecting all engines, which is why I've never noticed this before. The Nova Punch "NP_lfe_125m_K2XEngine" that I usually use is unaffected. Looking in the MM config cache this is what its config contains: 

		MODULE
		{
			name = ModuleEnginesFX
			PROPELLANT
			{
				name = LiquidFuel
				ratio = 0.9
				DrawGauge = True
			}
			PROPELLANT
			{
				name = Oxidizer
				ratio = 1.1
			}
		}

I did a search to make sure no other patch was modifying the base config file, which also contains the above.

I think there might be an issue with MFT and switchable engines, like those in Kerbal Atomics. When one of the KA-modified switchable nuclear engines is attached to my craft in the VAB, the MFT UI closes when a tank is added or removed. Not necessarily a severe or breaking issue (no need to rush to fix), it's easily worked around.

Most likely in need of a recompile.

It seems to work in the VAB, however some buttons on the context menu are sometimes doubled, such as Remove All Tanks and Show Tank UI. Nothing major but I haven't tested it extensively.

I am seeing the same thing here on KSP 1.12.2.3167.

Hi, love this mod, but is it dead? No update for final KSP version?

In the posts for his other mods, @taniwha mentioned he would get to updating those but didn't know when that would be, so he's probably just busy right now. I'd just give him some time.

In the meantime the mod seems to work in KSP 1.12 aside from some UI issues.

PSA: with a hex editor, you can get rid of the incompatibility warning that pops up when used with ksp 1.12.x.  I wouldn't normally presume to do this, but the author is, and has been for some time, otherwise engaged, and I think this is permitted by the license (if not, let me know).

When it first starts up, the mod invokes a function called CompatibilityChecker, which compares the current ksp version against some hard-coded values.  It expects the minor version to be no less than 8, and no more than 9 (i.e. ksp v1.8-1.9).  We simply replace the hard coded value for the upper bound.

In modularFuelTanks.dll, at address 0x273, replace 0x09 with 0x0C.

Voila.  No more popup, and the mod continues to works as it has in 1.12.x.

You're only providing information. Shouldn't be a problem. But if it causes any, that's on you to deal with.

(Should be okay though. Probably.)

Of course.  

Though I feel I should point out that any misbehavior is far more likely to come from the decision to use a mod on a version of ksp the author has not verified it works on, and that the mod itself explicitly warns against.  :D

As far as that goes, it'll work but there were (IIRC) UI bugs due to changes that were made.  Nothing that recompiling from the source wouldn't fix.

Has this mod gone offline? The link in the OP doesn't work for me. If it has gone down, is there another mod that lets me edit the content of the fuel tanks?

Doesn't seem like @taniwha is coming back to this. He still visits the forum but is not active in the community  and hasn't even posted anything in 2 years.

You could try using it anyway and ignore incompatibility warnings. AFAIK it'll still work. The incompatibility warning is triggered by a version mismatch. Literally all it does is check what version of KSP the mod has listed as being for and triggers the message. It's not a message from Squad, it's a 3rd party mod that many mods opted into. So, it should be functional but no guarantees.

There are other mods that let you edit the content of tanks. Real Fuels is a variant of MFT but with extra features. I think B9Switch lets you alter resources but not sure to what extent. SSTU lets you do it for SSTU parts but again, not sure to what extent. (when used with MFT or RF, those provide the only resource editing function)

I'll look into updating and compiling MFT myself. Can't say when that'll happen.

Thanks for the reply.Yeah I figured the mod is not actively updated but the main issue I have is, the link in the OP is broken on my end.

 

PS: It would be totally awesome if you or someone else took the time to care for this mod.

I have to get Visual Studios back up and running then ensure I can compile it and verify it works okay. It probably will as the source HAS been updated by the Realism Overhaul crew for Real Fuels. Although there were  some changes made to a section of the base MFT code that I can't abide... :mad:

Until then though, you can still download an older version...
