[1.8-1.9] Modular Fuel Tanks v5.13.1

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.
